The Leader in Factory Cooling & Industrial Ventilation

Open Space Cooler

(Evaporative Cooler)

The most effective and cost-efficient way to cool down any factory or industrial building. Our Open Space Cooler brand evaporative cooler series harnesses evaporative cooling technology to reduce air temperature and supply cool air.

Open Space Cooler (Evaporative Cooler)

Evaporative Cooler Built-In Features

UV Resistant

UV resistant all-weather new plastic moded casing ensures long service life of Evaporative Cooler

Multi Fan Blades

Multi-bladed fan design has more stability and lowers noise level.

Evaporative Cooler 
Control Features

Auto-Clean

Automatically cleans itself every 4 hours interval.

Cooling Pad Drying

Dries itself for 5 minutes after every operation.

On/Off Clean

Automatically cleans itself prior & after every operation.

Pre-Cooling

Prevent unwanted odor by wetting the pads before operate.

Program Start/Stop

Cooler can be set to start/stop automatically at pre-set time.

Water Shortage

Pump will automatically stop if water is lacking in the water basin.

Evaporative Cooler System Control

One Controller Controls all Units

Both Evaporative Cooler Series OS 18 and Series OS 30 can be managed by a single Wall Controller for up to 40 units of both series combined. This is made possible with the use of a hub a connector that links up to 4 coolers.

Set a Limit to Humidity

This is done by cutting off the pump operation once the humidity has risen above the set limit. The pump will re-start after the humidity falls back to the set limit.

We only use Munters cooling pad

The Open Space Cooler is equipped with the Munters CELdek cooling pads as standard. Munters CELdek pad has the following advantages :

High evaporation efficiency
Superb wetting properties
Low pressure drop when wet, leading to low operating costs
No water carry-over
Self cleaning
Strong and self supporting
Long life time
Munters CELdek is a product of Munters Europe AB, Sweden.

12°C Cooler Than Outside

Creates a cooling sensation as low as ΔTPTD-12°C depending on atmospheric conditions.

*ΔTPTD is perceived temperature drop
