Air Conditioner Accessories

How to choose the right cooler accessories?

If you're using an evaporative cooler or portable air conditioner, the right accessories can significantly improve its performance and extend its lifespan. Instead of blowing cold air randomly, connect a flexible duct and direct the airflow exactly where you need it — to a workstation, an event tent, or a specific zone in your warehouse.

Off-season protection

Evaporative coolers are seasonal equipment, and leaving them unprotected in winter shortens their life. Master winter covers are tailored for specific BC series models, while Trotec rain covers protect PortaTemp units even during outdoor operation.

Climate control and air distribution

With the TAC room thermostat, you set a target temperature and the cooler shuts off automatically once it's reached — an easy way to save energy. For Trotec PortaTemp units, advanced options are available: the PlanoPT through-door system lets you cool an adjacent room through a flat under-door passage, while the DualHex connector links two units into a single circuit.

Frequently asked questions

Do Master accessories fit Trotec coolers?

Not directly — covers and thermostats are designed for specific product lines. However, flexible ducts with a 305–310 mm diameter may be compatible across both brands. Check your cooler's outlet diameter before ordering.

Which flexible duct should I choose?

For spot cooling, insulated or black ducts work best — they minimise temperature loss along the route. If you need extra reach, go for a 7.6 m length.

Is a winter cover really necessary?

Yes — the evaporative pad is vulnerable to mechanical damage and moisture. A cover protects it from frost, dirt, and rodents. The cost of a cover is a fraction of the price of a replacement pad.
