Comfort HVACR Engineering Services (Pvt.) Ltd.
Source of chilled water for hotels, hospitals, pharmaceutical & textile industry, multi story buildings and industrial complexes, also used for process cooling. Multiple compressors with single & double refrigerant circuits. Factory assembled, internally wired, refrigerant charged and operationally tested before dispatch, including a built in chilled water circulation pump.
Comfort air cooled packaged water chillers (Series PAC) are a source of chilled water for all types of air conditioning applications: hotels, motels, restaurants, multi storey buildings, shopping arcades, office buildings, hospitals, pharmaceuticals, textile industry, industrial complexes, clinics, stores, brand outlets and cash & carries, as well as process cooling.
The chilled water is circulated through fan coil units, air handling units, air washer units, heat exchangers or directly through process machines that need cold water for cooling. The units can also be specially designed to cool brine/glycol solution for below freezing temperatures in very special process applications. Most suitable for air conditioning of multi storey buildings with individual temperature control in different areas.
Specially designed to operate at maximum efficiency in diverse tropical conditions. All models have multiple compressors with single & double refrigerant circuits and all necessary safety and protective devices for smooth, reliable and trouble free operation.
Manufactured in a wide range of 4 tons to 50 tons capacities. All units are completely factory assembled, internally wired, charged with operating refrigerant and operationally tested at the factory before dispatch, including a built in chilled water circulation pump. At site the unit only needs foundations, chilled water piping with accessories and a main power connection with circuit breakers.
Scroll compressors; multiple compressors with single & double refrigerant circuits.
MS shell and expanded U-tubes, insulated with 1" thick pre-expanded polyurethane.
Copper tubes mechanically expanded to aluminium plate fins; propeller type direct driven fans.
Chilled water circulation pump built in; factory assembled, internally wired, refrigerant charged and run tested before dispatch.
Protects the compressor motor winding from over heating.
Protects the unit in case of failure of any one or two phases.
Protects the compressor from over current operation.
Evaporator and condenser fan motors protected from over current operation.
Avoids simultaneous start of compressors and the resulting surge current (multi compressor units).
Protects the compressor from damage due to abnormal suction/discharge pressures.
Protects the compressor from damage due to lack of lubrication (semi hermetic compressors only).
To witness the compressor operating conditions (outdoor unit).
Eliminate transmission of unit vibration to the foundation/building.
On condenser coils, for longer life in sea line areas.
Stops the unit on failure of any one phase, under voltage or over voltage.
Keeps compressor discharge pressure within limits when ambient is low but cooling is still needed due to high inside temperatures.
Washable synthetic fibre media filter for extra air infiltration.
For CSF 500 to CSF 2000 models.
Double skin evaporator construction.
Microprocessor control.
