Model Series RERV Packaged Ventilation Units are designed for indoor and outdoor applications with efficiency and cost effectiveness in mind. Air volume capacity ranges from 250 to 20,000 CFM. Quality features include heavy gauge construction, weather resistant powder coat finish, quiet running forward curved blowers with ball bearings, adjustable v-belt drives, hinged access doors with perimeter gasket, and many other standard features. RERV Package Ventilation units incorporate an energy recovery wheel assembly to recover waste heat energy from the stale exhaust air to preheat the fresh air during the winter season, and reject heat energy, thus cooling the fresh air during the summer season. The energy recovery wheel assembly is designed to transfer the sensible or total energy between counter flowing supply and exhaust air streams. The assembly consists of a motor driven energy recovery wheel with heavy gauge galvanized steel casing. The recovery wheel itself is fabricated from a synthetic fiber-based substrate impregnated with non-migrating water selective molecular sieve desiccant. The recovery wheel assembly is UL tested and UL recognized as a component for heat recovery ventilators. The recovery wheel is ARI certified using the ASHRAE standard method of testing and ARI standard RERVFEAT DEC 08/04 EXHAUST AIR OUTDOOR AIR RETURN AIR FROM CONDITIONED SPACE SUPPLY AIR TO CONDITIONED SPACE

6 RERV/RERVX Optional Energy Saving Accessory Descriptions Re-circulation motorized two position damper for night set back A full capacity re-circulation damper with a two position spring return damper actuator can be factory mounted in the partition separating the return air plenum from the supply air compartment. This feature will allow for unoccupied / night set back requirements, providing that some means of remote duct mounted re-heat (and perhaps re-cool) has been designed into the ventilation supply air ducting system. Function: Supply and Exhaust fan motors: de-energized. Energy recovery wheel motor: de-energized. Exhaust discharge damper: closes. Outside air intake damper: spring returns to closed position. Re-circulation damper: powered open. Supply fan: energized by re-circulation damper full open end switch and supplies re-circulated return air back to the supply air duct system. Re-heat (and perhaps re-cool) external to the unit: energized as required from space thermostat or discharge temperature control as supplied by others. Option includes: Factory installed re-circulation damper, factory installed and wired two position damper motor with end switch. (Refer to Section 4, Optional Accessory Wiring Diagram 8) Fresh air ambient temperature control for free cooling Two fresh air ambient temperature controls can be factory installed to de-energize the energy recovery wheel above 55 F and below 75 F. Both temperature controls are field adjustable to suit design conditions. This option prevents unnecessary heating of supply air through energy recovery during these outdoor temperatures. Option includes: Factory installed 2 ambient temperature controls (Refer to Section 4, Optional Accessory Wiring Diagram 7) Fresh air enthalpy control for free cooling The fresh air enthalpy control has effectively the same function as the fresh air ambient temperature control. This option includes a fresh air temperature control and a logic controller with an enthalpy sensor. The fresh air temperature control energizes the energy recovery wheel below 55 F. The enthalpy control senses the enthalpy of the fresh air, which is a combination of the air temperature and relative humidity. The enthalpy control will energize the energy recovery wheel above the set point which is actually a range of fresh air temperature -humidity combinations, for example, from approximately 63 F 80% rh, to 82 F 10% rh, for setting A. The enthalpy control has 4 field adjustable settings to suit design conditions. Option includes: Factory installed enthalpy control and ambient temperature control (Refer to Section 4, Optional Accessory Wiring Diagram 6) OP2 DEC 08/04

35 RERV/RERVX Optional Energy Saving Accessory Descriptions Re-circulation motorized two position damper for night set back A full capacity re-circulation damper with a two position spring return damper actuator can be factory mounted in the partition separating the return air plenum from the supply air compartment. This feature will allow for unoccupied / night set back requirements, providing that some means of remote duct mounted re-heat (and perhaps re-cool) has been designed into the ventilation supply air ducting system. Function: Supply and Exhaust fan motors: de-energized. Energy recovery wheel motor: de-energized. Exhaust discharge damper: closes. Outside air intake damper: spring returns to closed position. Re-circulation damper: powered open. Supply fan: energized by re-circulation damper full open end switch and supplies re-circulated return air back to the supply air duct system. Re-heat (and perhaps re-cool) external to the unit: energized as required from space thermostat or discharge temperature control as supplied by others. Option includes: Factory installed re-circulation damper, factory installed and wired two position damper motor with end switch. (Refer to Section 4, Optional Accessory Wiring Diagram 8) Fresh air ambient temperature control for free cooling Two fresh air ambient temperature controls can be factory installed to de-energize the energy recovery wheel above 55 F and below 75 F. Both temperature controls are field adjustable to suit design conditions. This option prevents unnecessary heating of supply air through energy recovery during these outdoor temperatures. Option includes: Factory installed 2 ambient temperature controls (Refer to Section 4, Optional Accessory Wiring Diagram 7) Fresh air enthalpy control for free cooling The fresh air enthalpy control has effectively the same function as the fresh air ambient temperature control. This option includes a fresh air temperature control and a logic controller with an enthalpy sensor. The fresh air temperature control energizes the energy recovery wheel below 55 F. The enthalpy control senses the enthalpy of the fresh air, which is a combination of the air temperature and relative humidity. The enthalpy control will energize the energy recovery wheel above the set point which is actually a range of fresh air temperature -humidity combinations, for example, from approximately 63 F 80% rh, to 82 F 10% rh, for setting A. The enthalpy control has 4 field adjustable settings to suit design conditions. Option includes: Factory installed enthalpy control and ambient temperature control (Refer to Section 4, Optional Accessory Wiring Diagram 6) OP2 DEC 08/04

73 RERVLP Optional Energy Saving Accessory Descriptions Fresh air ambient temperature control for free cooling Two fresh air ambient temperature controls can be factory installed to de-energize the energy recovery wheel above 55 F and below 75 F. Both temperature controls are field adjustable to suit design conditions. This option prevents unnecessary heating of supply air through energy recovery during these outdoor temperatures. Option includes: Factory installed 2 ambient temperature controls Fresh air enthalpy control for free cooling The fresh air enthalpy control has effectively the same function as the fresh air ambient temperature control. This option includes a fresh air temperature control and a logic controller with an enthalpy sensor. The fresh air temperature control energizes the energy recovery wheel below 55 F. The enthalpy control senses the enthalpy of the fresh air, which is a combination of the air temperature and relative humidity. The enthalpy control will energize the energy recovery wheel above the set point which is actually a range of fresh air temperature -humidity combinations, for example, from approximately 63 F 80% rh, to 82 F 10% rh, for setting A. The enthalpy control has 4 field adjustable settings to suit design conditions. Option includes: Factory installed enthalpy control and ambient temperature control LP OP2

All interior cabinet surfaces shall be lined with 1 thick, 3 lbs/cu ft density foil faced insulation, with seems foil taped. Access doors and center partitions to be lined with 1/2 thick foil faced insulation. Access doors and panel to be lift off style. ENERGY RECOVERY WHEEL ASSEMBLY The energy recovery wheel assembly casing shall be constructed with heavy gauge galvanized steel, reinforced at sealing surfaces, removable end panels for drive access, inboard no-maintenance permanently sealed roller bearings for small assemblies, external pillow block bearings for large assemblies, and an adjustable non-contact neoprene bulb peripheral and inner seal. The wheel assembly shall slide in and out of the unit on a galvanized steel track for ease of inspection and maintenance. The wheel media shall be constructed of a corrugated synthetic fiber-based substrate impregnated with a non-migrating water selective 4A molecular sieve desiccant uniformly and permanently dispersed throughout the matrix structure. The wheel media shall be spirally wound to form a fluted honeycomb geometry so as to eliminate internal wheel bypass. Wheel layers that can be separated or spread apart by airflow are unacceptable due to the possibility of channeling and performance degradation. Face flatness of the wheel shall be maximized (+/ inches) in order to minimize wear on inner seal surfaces and minimize cross leakage. The wheel shall be complete with a purge section, minimizing cross over of return air into supply air, with a non-contact bulb seal. Wheels with large pore size desiccants like silica gel, that are coated, bonded, or synthesized onto the media or without a purge section will not be accepted. The wheel shall consist of evenly spaced galvanized steel spokes, a galvanized steel outer band, and an aluminum center hub. The standard drive system shall consist of a drip proof motor, fixed pulley, and link type drive belt constructed from a high performance polyurethane elastomer reinforced with multiple plies of polyester fabric. The drive pulley and belt shall drive the wheel from inside the assembly casing. Wheels with drive pulleys and belts that are exposed will not be accepted. Single phase drive motors shall have integral automatic reset thermal overload protection. Three phase drive motors shall have a manual reset thermal overload mounted in the unit control enclosure. Wheel media shall be in accordance with NFPA, and be UL tested and UL recognized as a component for heating and heating-cooling appliance accessories.
