Compact, air-cooled water chillers for server rooms, R&D labs, edge sites and high-density equipment. Add cooling capacity where the heat is, without turning it into a facility build-out.
For more than 50 years, WTG-Quantor has built compact temperature-control systems for European producers, where equipment rooms are small, floor space is limited and energy efficiency matters. That same engineering philosophy is exceptionally well suited to today's compute environment.
Built for around-the-clock operation with stable coolant temperatures. In continuous service at a Fortune 500 technology company since 2019.
Chiller, tank and pump in one compact, air-cooled housing, leaving more floor space for compute and adding capacity without a facility build-out.
i models use an inverter compressor, so cooling output follows a changing load. Fixed-speed models suit loads that stay steady.
Accessible components, a fault history on the controller display, an alarm contact on Chilly Max and MCK, and optional Modbus. Spare parts stocked in the USA and Germany.
From portable lab cooling to higher-density compute installations, choose the system sized around your actual heat load.



More cooling kW per square foot. Born in space-constrained European facilities.
All-aluminum microchannel coils and plate heat exchangers for efficient heat rejection.
Stainless steel tanks with level indicators and insulated piping for long equipment life.
R513A: non-flammable (A1) with a GWP of about 630, around 70% lower than R410A.
Top-discharge fans on Chilly Max and MCK simplify placement against walls.
Integrated centrifugal pumps at about 2.5–4 bar, depending on model. Variable-speed and high-pressure pumps on request for Chilly Max and MCK.
GPU, accelerator and electronics testing, plus experimental systems.
Dedicated liquid cooling without upgrading an entire central plant.
Compact cooling where floor space is limited.
Added capacity for a few high-density racks in an existing room.
Localized cooling for automated industrial systems.
Precision thermal management for compute-intensive analytics.
