• Diverse refrigeration-technical applications

Airmatik® –
the air-cooled chiller for outdoor use

Airmatik® is an air-cooled ammonia chiller for outdoor setup. It is easy to install and works with very low ammonia fill levels. It combines power, reliability and environmental compatibility.

Airmatik® will meet all your refrigeration-technical requirements

• Power from 150 kW to 900 kW in a usage area of -15 °C to +20 °C and at an outdoor temperature of up to +47 °C
• Ammonia as a refrigerant
• Low-noise axial fans
• Microchannel aluminium liquefier with high heat transfer and lowest refrigerant content
• Flooded evaporation system of stainless steel or titanium
• Speed-controlled electrical motors with high efficiency class
• Self-supported steel structure
• Management system, monitoring and continuous remote control
• Optionally with heat recovery
• The Airmatik® is tested under full load conditions in the factory before delivery

Recumatik® –
the innovative water-cooled chiller/heat pump

Recumatik® is a water-cooled chiller or heat pump that permits concurrent heat and cold production.

Complete heat recovery at concurrent heat and cold production
