Comfort HVACR Engineering Services (Pvt.) Ltd.
Air cooled split floor standing fancy air conditioner, two sections: an outdoor condensing unit and an indoor evaporator unit connected by site run refrigerant copper piping. Suitable for residential, commercial and industrial applications, including hazard-area/cement-factory-standard heavy gauge versions rated for +50C ambient.
Comfort air cooled split air conditioners, CSF series, comprise two sections: a condensing unit for outdoor installation and an evaporator unit for indoor installation, connected with refrigerant copper piping at site. Designed for maximum efficiency in tropical conditions and suited to residential, commercial and industrial applications.
Also available in a special design for hazard areas / cement factory standard: industrial grade heavy gauge condensers and evaporator units designed for high ambient T3 conditions (+50C), with 11-12 fins per inch for dusty environments.
Condenser motors and propeller fan blades are designed for an accurate air flow rate according to capacity, with pure copper motor winding and fan blades made from aluminium powder coated sheet. The weather proof condensing unit can be installed outside the building, at ground level or on a rooftop.
Evaporator units come in various designs: front body of the floor standing unit in stainless steel gold, non magnetic (models CSF 500 ~ CSF 2400 only), or at the floor in a separate free space.
Compressor, condenser coil, condenser fan, motor and all required electrical and refrigerant controls / accessories.
Evaporator coil, evaporator fan and motor, refrigerant control and operation control.
Heavy gauge galvanized steel sheets, degreased, de-rusted, phosphated and finished with electrostatic baked powder paint for corrosion resistance and long unit life. The evaporator unit has closed cell (Aeroflex) insulation to prevent heat losses. Front body of the floor standing unit in stainless steel gold, non magnetic, for a fancy look.
One or two hermetic or semi hermetic reciprocating/scroll compressors. Each compressor has a completely independent refrigerant circuit.
Forward curved centrifugal, double width double inlet fans, statically and dynamically balanced for noiseless operation. Blower fan and motor direct driven, with single and double shaft arrangement and multiple blowers.
Seamless copper tubes and aluminium plate fins, mechanically expanded for best fit and performance. Coils leak tested under water at a nitrogen pressure of 250 & 450 psig respectively.
Every unit is supplied with one set of 1" thick washable aluminium pre-filters. Filters of models CSF 500 to CSF 2400 are supplied loose for mounting inside the duct or at the return air grille.
Inside the condensing unit: phase failure relay, contactors, thermal overload relays, time delay relays (multi compressor units only) and fuses. Can be provided for remote installation, with remote display at the front door of the floor standing unit.
Front door electronic room thermostat: digital, programmable heating and cooling temperature control, with ON/AUTO, HEAT/OFF/COOL and 3-speed fan (optional) switches.
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.
Scroll to unfold the unit into front, side and plan views. The key catalogue numbers for that model sit beside the drawing.
