Quest 375 Dehumidifier 170L / Day

Quest 375 50Hz Dehumidifier is designed to keep relative humidity under control in demanding, large-scale spaces such as commercial grows, drying rooms or technical chambers with high vapour load. Its capacity of 170 litres/day (at 26.7 °C and 60% RH) makes it a powerful option for continuous operation without compromising stability.

High-efficiency technology (M-CoRR)

This grow dehumidifier integrates the patented M-CoRR technology (multi-coil design), aimed at achieving high efficiencies in its range: it delivers an energy factor of 3.6 L/kWh and, moreover, Quest stands out for a more compact design (20% size reduction) helping to reduce system thermal load.

Integrated digital control (and external control)

It includes integrated digital controls with adjustment in 1% increments, status/diagnostic indicators, maintenance alerts (filter change reminder after 2,000 fan hours) and dark mode for light-sensitive environments. It also allows external control via 24 V input (disabling the internal sensor when active).

Flexible installation: floor or suspended

Can be placed as a standalone unit or mounted suspended from the ceiling using 3/8" threaded rod, taking advantage of its integrated lifting/suspension points to optimise space.
