Mark MISTRAL MDX: Industrial VRF Air-to-Air Heat Pump for Large Spaces

The Mark MISTRAL MDX is a high-performance industrial VRF air-to-air heat pump system, purpose-built to deliver energy-efficient heating and cooling for large commercial and industrial premises. This robust solution combines an outdoor heat pump unit with a compact indoor air heater/cooler, ensuring powerful climate control. Thanks to a wide range of configuration options, the system can be tailored precisely to the requirements of your building and the preferences of its users.

With generous pipe lengths (up to 90 metres for the MDX 33 and up to 170 metres for the MDX 56) and an extensive operating temperature range, the MISTRAL MDX is ideal for varied applications. It’s well-suited to industrial units, garages, warehouses, workshops, distribution centres and showrooms.

PinTherm Mistral Thermostat for Seamless Control

The PinTherm Mistral is a digital room thermostat with a weekly programmable timer, designed to work seamlessly with the Mark MISTRAL MDX heat pump. It’s also suitable for managing air-to-water heat pumps when used with the new Mark Tanner MDA+ air heater/cooler.

Equipped with an on/off contact and a 0–10 VDC output, the thermostat supports easy monitoring and adjustment via Modbus or Ethernet, enabling integration with most Building Management Systems (BMS).

What Is an Industrial VRF Air-to-Air Heat Pump System?

A VRF (Variable Refrigerant Flow) system is an efficient climate control solution consisting of an outdoor heat pump and one or more indoor units, connected via a refrigerant circuit. Functioning as an air-to-air heat pump, it cools spaces by removing warm air and expelling it outside, while heating is provided by reversing the cycle.

VRF—sometimes referred to as VRV (Variable Refrigerant Volume)—means the system can adjust the amount of refrigerant used depending on demand. In the MISTRAL MDX, an expansion valve within the indoor unit regulates refrigerant flow to manage both output and discharge temperature. This allows for precise and efficient control, making it an excellent choice for large-scale climate management in buildings such as warehouses, industrial halls, distribution centres, and showrooms.
