Why standard AC fails in the Middle East

Extreme heat, sand and unstable grids break ordinary cooling

55°C ambient

Desert sites regularly exceed 50°C. Ordinary units trip or lose capacity; HCK runs continuously up to +55°C.

Up to +55°C

Sand & dust (IP55)

Fine desert dust clogs filters and shorts electronics. IP55 sealed enclosure keeps the cooling loop clean.

Voltage fluctuation

Grids swing 200–240V. HCK tolerates ±20% and offers 48V DC for solar/telecom sites off the mains.

±20% / 48V DC

Solar radiation

Direct sun heats cabinet skins. Closed-loop cooling holds interior at 25°C regardless of radiation load.

FAQ

Extreme heat, sand and unstable grids break ordinary cooling

Can HCK cabinet AC start and run at 55°C ambient?

Yes. HCK units are rated for continuous operation from -40°C to +55°C ambient, so they keep cooling through Middle Eastern summer peaks without tripping.

How do you handle desert sand and dust?

The closed-loop IP55 enclosure separates the cooling circuit from outside air. Condenser/evaporator fins stay clean; only periodic fin cleaning is needed.

What voltages are supported?

Standard 220V±10% 50Hz; 48V DC for solar/telecom; 208/230/240V configurable. Tell us your site voltage and we match it.

Do you provide export certifications?

Yes. HCK cabinet ACs are built to industrial standards and support CE and other export certifications per market. Email INFO@ZJHCC.COM.

Is component sourcing documented?

Yes. HCK issues a documented BOM with sourcing records per project; units use a rotary compressor, R410A refrigerant and high-efficiency motor.
