Trotec TTK 170 ECO (Black/White, 52L/Day)

What room size can this dehumidifier effectively handle?

This unit effectively covers rooms up to 90m² or volumes of 230m³. The 52L daily extraction capacity makes it suitable for large spaces like workshops, basements, warehouses and commercial areas. For optimal performance, ensure adequate air circulation around the unit and consider room insulation levels which affect moisture accumulation rates.

How does the hot-gas defrost system work and why is it important?

The hot-gas defrost system automatically prevents ice formation on the evaporator coils when operating at low temperatures. It redirects hot refrigerant gas to melt any ice buildup, maintaining consistent performance down to 5°C. This is crucial for unheated spaces where standard dehumidifiers would freeze up and stop working effectively.

Can I leave this running unattended for continuous operation?

Yes, you can operate it continuously in two ways. The 7L condensate tank has automatic shutoff when full, requiring periodic emptying. Alternatively, connect the external drain hose for truly unattended operation where condensate drains away automatically. This makes it perfect for ongoing site drying, basement moisture control, or commercial applications requiring 24/7 operation.

What's the noise level and is it suitable for occupied spaces?

The unit operates at 56dB, which is comparable to moderate conversation levels. Whilst not silent, it's acceptable for most commercial and industrial applications. For noise-sensitive environments, consider operating during off-hours or using the lower speed setting which reduces both noise and power consumption whilst maintaining effective moisture removal.

How accurate is the humidity control and what range can it achieve?

The digital hygrostat provides precise humidity control with real-time display of current conditions. It can reduce relative humidity to approximately 30%, making it suitable for applications requiring very dry conditions. The adjustable target humidity settings allow you to maintain specific moisture levels automatically, with the unit cycling on and off to maintain your desired environment.

Is this suitable for construction sites and rough environments?

Absolutely. The steel housing construction, shock-resistant structure and trolley design with large wheels make it ideal for construction sites. The cable hook prevents damage during transport and the robust internal components withstand harsh conditions. The hot-gas defrost system ensures operation in unheated buildings, making it perfect for site drying and construction moisture control.

What maintenance is required and how often?

Maintenance is minimal thanks to the robust design. The air filter should be cleaned regularly - it's washable for easy maintenance. The integrated operating hours counter helps track usage for maintenance scheduling. The rotary piston compressor design is inherently reliable and allows the unit to be transported or stored in any position without damage to internal components.

Does it come ready to use with UK power supply?

Yes, it's supplied with a standard UK 13A plug that's fully compliant with UK electrical standards - no adapter required. It operates on 230V mains power, consuming 820 watts at 3.7 amps. The unit is ready to plug in and use immediately upon delivery, making it convenient for both domestic and commercial applications across the UK.
