Outdoor Air Chiller

1. Machine Room-Free Outdoor Installation | Cut Down Upfront Capital Cost

Installed directly outdoor, the modular air source heat pump requires no dedicated equipment room, cooling tower, well drilling or underground pipe burying, effectively slashing customers’ initial construction and investment expenses greatly.

2. Superior Energy Efficiency & Eco-Safe Operation

Save up to 75% power consumption vs pure electric heating systems. Unlike fossil fuel-fired boilers, our HVAC heat pump realizes zero combustion and zero waste gas discharge, eliminating fire & explosion hazards for full operational safety and eco compliance.

3. Flexible Modular Configuration & Phased Investment Solution

Supports cascade combination of max 16 modules to match variable building heating & cooling load for commercial & industrial HVAC projects;
Easy capacity expansion allows phased procurement and staged investment to fit customers’ incremental project demands.

4. Ultra-Wide Working Ambient Temperature for All-Climate Application

Stable heating running: -30℃ ~ 25℃ ambient temp;

Reliable refrigeration performance: -30℃ ~ 48℃ ambient temp, adaptable to extreme cold and high-temperature regions globally.

5. NB-IoT Intelligent Auto Control | Zero Full-Time On-Site Attendance

Real-time operational monitoring + automatic load-based capacity adjustment via smart control system. No dedicated staff on duty required, drastically cutting long-term manpower expenditure for end users.

6. Comprehensive Multi-Protection System for Stable & Reliable Running

Graded sequential startup across separate modules lowers startup current shock to power grid. Equipped with complete multiple safety protections; the system triggers instant automatic alarm once any malfunction occurs to safeguard unit safe operation.
