When outdoor temperatures drop below -15 °C, most industrial heat pumps do not deliver what their specification sheets promise. Capacity falls. Processes slow. Operations pay for the gap between rated performance and real-world output.
AirTreater systems are built around a different principle: guaranteed nominal heating and cooling capacity at every outdoor temperature, from mild autumn conditions down to -28 °C. Not estimated. Not typical. Guaranteed.
When heat pumps fail, operations pay the price
Conventional heat pumps are rated under optimal conditions. When temperatures drop, so does output. At -15 °C, a system rated at 90 kW may deliver considerably less. For industrial processes, construction sites, and critical infrastructure, that shortfall is not an inconvenience. It is a measurable operational failure.
The consequences are direct: lost production time, process restart costs, emergency procurement, and in the most critical applications, safety exposure. A cold-weather heat pump that cannot hold its rated output is not a heating solution. It is a liability.
- Process interruptions caused by heating or cooling shortfall carry real restart costs
- Emergency equipment hire in winter conditions is expensive and rarely immediate
- Derated performance at low temperatures is a known industry problem that most suppliers do not address in their sales materials
- Sites in northern climates face exactly the conditions where conventional systems are least reliable
The problem is not weather. The problem is equipment that was never designed to perform in it.
Full rated capacity from mild to -28 °C
AirTreater Čáhci is an air-to-water heat pump engineered for liquid-cycle energy distribution in large industrial and commercial applications. It maintains 120 kW of nominal heating capacity at -15 °C using compressors alone. No auxiliary heat strips. No performance compromise.
The heat pump operates down to -28 °C. When temperatures fall further, the integrated backup system activates to guarantee at least 300 kW of heating capacity even without external electric power in hazardous situations. Maximum output reaches 420 kW across the full operating range, maintained down to -15 °C.
- 120 kW nominal capacity at -15 °C on compressors only
- 420 kW maximum capacity maintained down to -15 °C
- At least 300 kW guaranteed at -28 °C and below with integrated backup system active, even without external electric power in hazardous situations
- Outlet water temperatures of +75 °C enable direct integration with existing high-temperature hydronic distribution systems
For process cooling applications, AirTreater Prosea delivers free cooling energy-efficiently without engaging compressors during cold-weather conditions. The free-cooling function eliminates the primary mechanical failure point of conventional chiller systems while significantly reducing energy consumption during extended cold-weather operation. Prosea systems are designed per project and site to meet each application’s specific requirements.
This is not a performance claim. It is the operational baseline every AirTreater system is designed and guaranteed to meet.
Portable, containerized, and ready to deploy
Both AirTreater Čáhci and AirTreater Prosea are delivered in standard shipping containers, pre-configured and ready to connect. There are no permanent civil works requirements, no plant room commitments, and no long installation lead times.
The container connects on site in a single working day. Where no heat distribution network is required, the system is fully operational within 4 hours of arrival.
- Container connection completed in one working day
- Full operational status achieved within 4 hours
- No permanent infrastructure commitment — the system relocates when the project or site requires it
- Suitable for construction projects, temporary industrial sites, remote operations, and permanent industrial facilities requiring rapid deployment
When operational requirements change, the system moves with them. Asset redeployment requires no specialist civil works and no write-off of fixed infrastructure investment.
Remote monitoring and 24/7 support included
Every AirTreater system is managed via an automated remote management platform, providing real-time operational data and full settings control through a standard web browser. Site visits are not required to monitor performance or adjust parameters. Named end users can also have access to the automation system.
Operators have a live view of system status, outlet temperatures, and operational data from any location, at any time. Settings are adjustable remotely, without requiring on-site personnel.
- Real-time operational visibility via automated remote management platform, accessible from any browser
- Remote settings adjustment without site attendance
- 24/7/365 help-desk support through AirTreater’s service centre
- Designed for unmanned and remote sites where on-site response time is not guaranteed
For operations running continuous processes, support availability outside business hours is not a premium add-on. It is a baseline requirement. AirTreater’s 24/7/365 help desk is available every day of the year.
Get guaranteed performance for your site
The specification is straightforward: guaranteed nominal heating or cooling capacity at all outdoor temperatures, containerised deployment with full operational readiness within 4 hours, and continuous remote management and support.
If your site requires reliable industrial heat pump performance through Finnish winters or equivalent cold-climate conditions, the next step is a direct conversation with AirTreater’s technical team.
- Discuss your site’s heating or cooling capacity requirements and outdoor temperature range
