TECHNICAL DESCRIPTION

CASING

The casing is made of galvanised sheet steel with high-efficiency internal lining for optimised thermal and sound insulation of the unit. The fan coil unit is available with Euroclass level B-s2-d0 insulation (in compliance with EN13501-1). To minimize the dimensions, the units are equipped with high- efficiency heat exchangers with very high cooling capacity. The condensate drain pan height is optimised. Mounting holes and slots quicken hanging operations.

Coil

Unit coil using the latest developed wide seam blue hydrophilic aluminum fin, advanced mechanical tube expanding process, ensure copper tube optimally contacts with aluminium fin. Wide seam hydrophilic aluminium fin provides sufficient heat transfer channel for heat exchanger, wide impeller provide uniformly air velocity environment for heat transfer.

It makes the heat transfer more complete, which ensures the cooling capacity per input power of 42CT outperforms other similar products. Metal sheet casing prevents any damage on header and coil connections.

• Aluminium fins mechanically bonded by expansion onto copper tubes
• With 7 mm copper tubes and special coil design, unit can supply high cooling and heating capacity with minimized dimensions even in bigger size models
• ¾” threaded female water inlet and outlet connections for all sizes
• Operating pressure of 16 bar

Maximum hot water inlet temperature

• 4-pipe application: 90°C
• 2-pipe application: 90°C

Fan

42CT unit equipped with newly designed wide and large diameter impeller, low speed forward multi-blade. The fan casing is strengthened with reinforcing ribs for additional strength. It adopts NSK bearings, ensuring small vibration and low noise in operation. One to four-wheel fans depending on the unit size.

Electric Motor

The 42CT has 3 speed fan motor with totally enclosed casing structure and it has great advantages in efficiency, noise and energy saving.

Fan motors of all types are

• Asynchronous motors, 4 poles with internal overload protection
• Permanent split capacitor
• Power supply: 220V-240V/1Ph/50Hz
• Level of Protection: IP20
• Class B insulation

Electrical Box

Electrical Box is standard in 42CT for all models. The unit is factory-fitted with an electrical box with the 3 standard speeds connected to a terminal strip. With the electrical box, the installer can connect the unit to a terminal board. The electrical box can be opened with a screw driver. Electrical box can be mounted to both sides of the units thanks to its long wiring.

Condensate Drain Pan

A condensate drain pan is cold roll steel with powder coating and drain pan has its own angled surface so that condensate can be drain out smoothly. Drain pan design enhances the strength of drain pan, and avoid drain pan deformation in transportation.

• The drain connection diameter is 3/4’’ threaded nippel
• 6 mm flexible elastomeric rubber foam insulation
• Fire rating B-s2-d0 in compliance with EN13501-1
• Stainless steel and extended lenght drain pans are optional

Plenums

Factory mounted rear air plenum is standard in all sizes and models of the unit for a better quality and appearance. Along with the air plenum box, filter is also supplied in standard and ISO Coarse %40 filter (in compliance with ISO 16890) is optional for a better indoor air quality. Unit can also be supplied with bottom plenum option.

Air Filter

All the models are supplied with standard factory installed washable nylon mesh filter with aluminium frame. With its special design, filters can be removed on both rear or bottom side of the unit easily. The unit can also be supplied with ISO Coarse %40 filter (in compliance with ISO 16890) for a better air quality as an optional.

Filter Access

Filters can be easily removed from both the back and the bottom side of the unit without any necessity of extra equipment thanks to the clamps.

• Unit with rear plenum
• Unit with bottom plenum
