PMR series packaged air conditioners are designed to operate in a wide ambient temperature range between 0 F (0 ) to F (.7 ). Two independent refrigeration circuits are provided where two compressors are used. PMR units are designed,rated and manufactured in accordance with HRI 0/40 and 340/360 standards.

Each unit is fully factory tested before dispatch and is ready for installation. ll that is required on the site is to connect ducts, drain lines, main power supply and field wiring to the thermostat. This greatly reduces the installation work and cost. SKM provides qualified service and stock of replacement parts in all major cities of the G... countries, Egypt, Jordan, and Pakistan.

3 SKM Packaged ir onditioning Units PMR Series R40 General Features The PMR Series is a modern, diversified and environment friendly series of packaged air conditioners which use R40 refrigerant. The PMR Series Packaged ir onditioners are yet another new unique series from SKM incorporates many salient features which, together, provides a heavy duty, robust, long lasting commercial unit meant for high end residential and commercial applications. The PMR series models combine high efficiency condenser and cooling coils, evaporator blower and heavy duty motor in addition to premium safety and operational controls. The complete PMR packaged unit provides an extremely rugged, long life, energy efficient, self contained packaged air conditioner that will provide cooling with higher efficiency over a long and extended life. What makes PMR series yet another model in the top class range of SKM products is the use of: High efficiency totally sealed scroll hermetic compressors. Totally enclosed,lass F insulated, condenser and evaporator fan motors. Heavy duty condenser and evaporator coils optimised in design for longlife maintenance free operation. abinet construction specifically designed for Gulf climates. Electronic control board for the unit operation. Typically, much heavier gauge tubing and thicker fins for ruggedness and long life. Main omponent Features The common standard features of all PMR series packaged units include the following. ompressors ompressors used in PMR packaged unit series are hermetically sealed, compact scroll with the following features: High Efficiency. Quiet operation, Low Sound levels. ompact and light. Limited wear. 70% fewer moving parts than comparably sized reciprocating compressors. Unique ability to hadle liquid refrigerant. Suction gas motor cooling. Suction screen. entrifugal oil pumps with filter and magnet. razed fittings or Rotalock options. Two refrigerant circuits on larger units provides efficient part load. No internal valves. ondenser oils ondenser coils are manufactured from cross fin Waffle Louvre and HiX seamless copper tubes mechanically bonded to aluminium fins to ensure optimum heat transfer. ll coils are tested against leakage by high air pressure under water. n integral subcooling circuit is incorporated in the lower section of the condenser to increase system capacity. The additional condenser surface provides more cooling using less energy at no additional cost. ondenser Fans ondenser fans are propeller type with aluminium alloy blades and are directly driven by electric motors. Motors are Totally Enclosed ir Over (TEO), six pole or four pole with lass F insulation and minimum IP4 protection. The TEO and lass F insulation features ensure long life and are unique to SKM. The condenser fans are individually statically and dynamically balanced at the factory. omplete fan assembly is mounted downward on the strong and acrylic coated fan guard for the smaller units. For larger units fan, assembly is separate and provided with suitable acrylic coated fan guard. Evaporator Evaporator coils are manufactured from HiX seamless copper tubes mechanically bonded to aluminium cross wave fins to ensure optimum heat transfer. ll evaporator coils are tested against leakage by high air pressure of 40 psig (0 kpa) under water. oils conform to HRI40. Evaporator Fan & Drive Evaporator fans are forward curved centrifugal double inlet, double width, statically and dynamically balanced. earings used in the fans are self aligning and lubricated for life. Evaporator fans are belt driven and use V belts with an adjustable variable pitch motor pulley resulting in an accurate fan air flow adjustment. Fans are driven by Totally Enclosed, IP Protected, 4 pole lass F insulated electric motors. The motors are factory wired to the control panel where the motor starters are located to control the operation of the motors. The motors conform to relevant IE standards. asing and Structure The unit casing used in PMR series is made of hot dip galvanized (zinc coated) steel sheets, conforming to JISG 3 and STM, which is phosphatized and baked after an electrostatic powder coat of approx. 60 microns. This finish and coating can pass a 000 hour in % salt spray testing at 9 F (3 ) and 9% relative humidity as per STM 7. 3

4 SKM Packaged ir onditioning Units PMR Series R40 The evaporator section is insulated from all the sides with thick fiber glass insulation with extremely tough and durable black composite surface. The insulation cum sound liner meets the fire requirements of NFP90 & 90 and is secured with mechanical fasteners in addition to water resistant adhesive. Refrigerant R 40 Why 40? R40 has a higher volumetric cooling capacity compared to R and has better thermal exchange properties. This results in overall performance gains in terms of system efficiency. The greater density of the vapour in R40 permits higher system velocities, reduces pressure drop losses and allows smaller diameter tubing to be used. In other words a smaller unit can be developed using a smaller displacement compressor, less coil and less refrigerant while maintaining system efficiencies comparable to current day R equipment. enefits No ozone depletion potential or phaseout date Using chlorinefree R40 with zero Ozone Depletion Potential (ODP) helps protect both the environment and your investment. That s because new equipment using R40 faces no mandated phaseout date over a 0 to year equipment life expectancy. Reduced service costs R40 refrigerant has no significant glide. If a leak occurs, only the lost refrigerant must be replaced. ttention points Pressure level:.6 times of R. Lubricating oil: Ester Oil absorb moisture easily (Never mix with mineral oil). Tools exclusive for R40. Never mix R40 with other refrigerant. Driers, valves and even copper tube must be approved for use with R40. Never allow refrigerant cylinders to exceed 60. ontrol Panel The PMR packaged ir onditioners are provided with IP4 control panel enclosure comprising all starting, operating and safety controls. The following are the standard components used in all PMR series units. Starting contactors for compressors and motors. Internal overload protection for compressors. Internal OR External overload protection for the motors (depending on the model). Electronic control board for unit operation. Diagnostic LEDs on the control board for easy troubleshooting. ompressor short cycling protection. ontrol switch for unit on/off. ontrol circuit breaker. Power and control circuit terminal blocks. High pressure protection. Low pressure protection.
