SKM Air Conditioning

The APCY-P is SKM's flagship premium-efficiency air-cooled screw chiller, covering 105 to 360 TR (369–1,265 kW) on R-134a refrigerant.

The APCY-H is the widest-capacity model in SKM's APCY air-cooled screw range, spanning 81 to 519 TR (285–1,825 kW) and covering both 50 Hz and 60 Hz power supplies — the broadest market reach in the lineup.

The ACMR is SKM's air-cooled scroll chiller range, using hermetic scroll compressors on R-410A refrigerant to cover 8 to 279 TR (28–981 kW) across 56 models on 50 Hz and 60 Hz.

The STR is SKM's water-cooled centrifugal chiller range, spanning 200 to 2,700 TR on R-134a in two efficiency tiers: the U-Type ultra-high-efficiency variant achieves COP 6.9 (0.509 kW/TR) and the E-Type high-efficiency variant achieves COP 6.4 (0.549 kW/TR) at AHRI conditions.

The HMAH is SKM's hygienic modular air handling unit, built to the requirements of VDI 6022 and DIN 1946 — the German and European standards that define hygienic design, construction, and maintenance access for ventilation plant serving sensitive environments.

The APCY-E replaces the conventional copper-tube condenser coil with aluminium microchannel heat exchangers (MCHE) as standard, making it the most compact and lightest chiller in SKM's air-cooled screw range at equivalent capacity.

The WPCY is SKM's water-cooled screw chiller, spanning 82 to 375 TR (288–1,318 kW) on R-134a.

The APCN-S is the model in SKM's air-cooled screw range specifically rated to operate at ambient temperatures up to 55 °C (131 °F), three degrees higher than the standard 52 °C ceiling on the APCY family.

The APCN-V brings integrated variable-speed drive technology to SKM's air-cooled screw platform: the frequency inverter is built directly into the compressor casing rather than bolted on externally, eliminating the auxiliary cooling circuit that conventional external VFD installations require.
