Calorex DH 75AX Dehumidifier

Floor standing high capacity 86L dehumidifier

The Calorex DH 75AX is a high-capacity dehumidifier that can remove up to 86-litres of water within 24 hours. It is a self-contained, fully automatic unit with an integrated humidistat and a 15mm condensate outlet for permanent drainage. The Calorex DH 75AX is a floor-standing dehumidifier, perfect for humidity control in data centres, warehouses, museums, galleries, offices, archives, sports halls, gyms, and more.

This commercial dehumidifier has a low temperature operating range of 5-35°C, and a hot gas defrost function. It works well all year round - effective in unheated areas and during colder weather. The Calorex DH 75AX also recovers heat to the air when running, helping to raise the ambient temperature for the comfort of occupants and dehumidification efficiency while reducing other heating costs.

The Calorex DH 75AX dehumidifier is a robust and durable unit. It has a polyester-coated evaporator and condenser, and a stove-enamelled aluminium cabinet that offers resilience in demanding areas and ensures reliability in performance. The Calorex DH 75AX floor-standing dehumidifier is versatile and practical, with a range of excellent additional options available, such as a remote humidistat for control away from the unit, and an 8.9kW low-pressure hot water coil for extra heating power.

86L/24Hr Water Removal: This high-capacity dehumidifier offers efficient performance, with cooling and compressor operating times based on an internal microprocessor calculation to optimise performance.

Integral Humidistat: Featuring user-friendly remote controls, the humidistat allows you to set the desired humidity level. When the relative humidity in the space varies from the set level, the machine will automatically turn on or shut down.

Drainage Hose Connection: Allows a hose to be connected so that condensate can be drained out of the space through an external wall, meaning there is no tank to empty.

Robust Build: This dehumidifier is built to a high standard, with high quality components and a long-lasting stove enamelled aluminium cabinet, designed to withstand tough environments. Suitable for data centres, warehouses, storage facilities, museums and galleries, offices, archives, sports halls, gyms and more.

Self Contained / Fully Automatic: The Calorex DH 75AX can run continuously and unattended so that it can extract the maximum amount of excess moisture from a room.

Hot Gas Defrost: The DH 75AX has an automatic defrost function built into the system. If the evaporator reaches near freezing temperatures, the defrost function flushes the evaporator with hot gas to melt any formed ice. Once a preset temperature is reached, the dehumidifier resumes regular operation.

Low Noise: The quiet centrifugal fans with two speeds operate at just 53dB, which is the same volume as a normal conversation - perfect for public spaces.

Optional Accessories Available: You can buy a remote humidistat, which can be wired to the dehumidifier with up to 100m of cable (1mm SQ cable), and allows control of the set humidity level away from the unit. There is a floor stand, which allows the dehumidifier to be placed on the floor and against a wall, instead of being mounted. We also have a low pressure hot water (LPHW) option for the DH75AX model. The LPHW option (low pressure hot water) is an 8.9kW heating coil which can be added inside the unit. It works the same as a radiator in your house - so it needs to be plumbed into a boiler system. It provides a source of heat which warms the air, allowing it to absorb more moisture that the dehumidifier can extract, and it provides a heat source for occupants within the space.
