Air-cooled modular chillers produce chilled water without cooling towers, which makes them the go-to choice where water is scarce or plant-room space is limited — a very common situation across the Middle East and Africa. Modules are simply added in parallel as the building load grows.
Our factory-direct modular scroll chillers come in 30, 65 and 130 kW modules with free combination of up to 32 units. Run time is distributed evenly across modules to extend service life, and high-efficiency heat exchangers minimise energy losses.
- 30 / 65 / 130 kW modules — combine up to 32 units in parallel
- R410A refrigerant, EER up to 3.26 and SEER up to 3.95
- Even run-time distribution across modules extends service life
- No cooling tower needed — ideal for water-scarce regions
- Heat-pump versions provide winter heating from the same unit
- Suitable for hotels, malls, office buildings, factories and hospitals

Specifications verified: July 2026 — factory datasheets.
30, 65 and 130 kW modules combine on one water loop — up to 32 of the 30/65 kW modules or 16 of the 130 kW modules, reaching 2,080 kW system capacity. EVI heat-pump modules keep heating down to -30 °C ambient with leaving water up to 60 °C.

How many chiller modules can be combined?
The 30 kW and 65 kW modules combine up to 32 units on one water loop, while the 130 kW module combines up to 16 units — in both cases the system reaches up to 2,080 kW of cooling capacity. Run time is distributed evenly across modules, and extra modules can be added later as the building load grows.
Do you offer cooling-only versions?
Yes. The CLS-F30/65/130CW/ZR1 cooling-only series covers 33.15, 65 and 130 kW per module, with EER up to 3.38 on the 65 and 130 kW sizes. Up to 16 of the 130 kW cooling-only modules can be combined, which suits Middle East and African projects where winter heating is not required.
Can these chillers run in cold climates?
For cold regions we supply the EVI (enhanced vapour injection) heat-pump series CLS-FE35/75/155HW/ZR1A, which keeps heating at ambient temperatures down to -30 °C and delivers leaving water up to 60 °C. Rated heating capacities are 36, 77 and 155 kW at A7/W45 conditions, with IPLV(H) values of 2.82–2.93.
What compressors do these chillers use?
The modular scroll chillers use Copeland hermetic scroll compressors — one to four per module depending on size — and the EVI low-temperature series uses Copeland EVI scroll compressors designed for vapour injection. The exact compressor model fitted to each module size is listed in the factory datasheet, which our team shares on request.
