Product Details
This dehumidifier operates on the desiccant principle. This ensures not only reliable and high performance at low temperatures, but also allows reaching a lower dew point compared to condensation dehumidifiers.
Thanks to internal heat recovery and electronic adjustment of the dry air flow rate, the TTR 3700 takes its place among the most cost-effective desiccant dehumidifiers, just like the other TTR desiccant dehumidifiers!
Its robust technology developed to industrial standards makes the TTR 3700 a reliable partner in dehumidification even under the most demanding conditions.
- "Made in Germany" quality, robust units
- High dehumidification capacity even at low temperatures
- Reliable, washable and mechanically robust silica gel adsorption rotors
- Internal heat recovery
- Electric regeneration heating
Features of the TTR 3700 dehumidifier:
- Steel housing
- Voltage input
- Rotor rotation monitoring (rotor and drive)
- Overheating protection – can be switched on/off (air regeneration)
- Operating temperature adjustment (air regeneration)
- Filter monitoring (air flow and warning lamps)
- Duoventic control*
- Adjustable air return (very easy to change)
- External On/Off connections
- Hygrostat connection
- Potential-free contacts (operation, fault, filter)

How It Works?
Humid air, slowly rotating silica gel coated desikant rotordan passes through; moisture is absorbed by the rotor. A small segment of the rotor is continuously dried with heated regeneration air, and the moisture is expelled through a separate duct. This way eksi sıcaklıklarda bile and operates continuously even at very low humidity targets.
