Why relative humidity decides mushroom yield

Mushrooms are mostly water. When room RH drops, caps crack, pins dry out and weight is lost at harvest. Holding RH steady — usually 85–95% depending on the stage — needs a humidifier sized to the room and controlled by a reliable RH sensor.

Matching an evaporator to its condensing unit

An evaporator and condensing unit only perform as a pair. Sizing starts with the heat load of the room: walls, product, people, lights and fresh air. A matched pair reaches set point faster, defrosts cleanly and uses less power.

Fresh air and CO2: the hidden climate factor

Growing crops and stored produce release CO2. Without fresh-air exchange it builds up and slows growth or ripening. A CO2 sensor linked to a duct fan brings in fresh air only when needed, protecting both the crop and your cooling load.

Engineering by Bandhuja

Bair is the engineering and manufacturing company of the Bandhuja group. Our equipment grew out of running real mushroom plants, cold rooms and laboratories — so every unit is built for the conditions it will actually work in, and supported by people who understand the process behind it.
