Designed and optimised for R407C, this range of 20 air-cooled condensing units and heat pumps covers the range of 3-80W in cooling mode. Standard head pressure control and mains isolator. Small footprint and slimline design are ideal for wall-mounted installation.

A large surface area coil is ideally positioned to optimise airflow and heat transfer. Units feature axial flow fan assembly with low noise sickle type blades and inlet ring. External rotor motor allows the use of a low power output, single phase, speed controllable motor to power the fan.

Fitted with a thermostatic expansion valve and check valve assembly to prevent short circuiting of refrigerant, together with large capacity suction accumulator and a reversing valve.

Benefits

Head pressure control optimising performance.
Microprocessor system allows indoor unit to be matched to CU, communication via 2-wire link.
Hot gas bypass valve for capacity control – modulates down to 40% of full capacity.
External rotor motor allows use of low power output single phase speed controllable motor with inbuilt thermal overload.
Thermostatic expansion valve and check valve assembly prevents short circuiting of refrigerant.
Scroll compressors for reduced sound, higher efficiency and lower electrical starting currents (CUS5 – 12 and CUS15 – 30D).
Head pressure control optimising performance.
External rotor motor allows use of low power output single phase speed controllable motor with inbuilt thermal overload.
