Daikin AKZ439 – Oil Cooling Unit

~ scroll down to find the part you need ~
Daikin Industries are the market leaders in environmentally responsible hydraulic pumps, valves and power packs for commercial and industrial applications.

Daikin have focused on the process lines in a factory where 45% energy is consumed generally. Daikin’s unique oil hydraulic systems which integrates oil hydraulic control and inverter motor technologies will be able to reduce power consumption significantly.

High accuracy oil temperature control

Acclaimed ±0.1°C oil temperature control has been extended to cover an even wider range.

 Refrigerant gas leakage detection alarm function

An alarm signal is output when the refrigerant gas

would be leaked (as cooling circuit failure).

Oil temperature warning function

A warning signal can be output when the oil temperature or air temperature strays outside arbitrarily setting range.

Auto tuning function

This function substantially cuts the time taken for adjustment during trial operation by automatically setting the gain when oil temperature control is not stable in the factory setting status or when optimization is required.

999-hour timer function (ON timer)

The operation start time can be set from 0 to 999 hours in one-hour units.

Preventive maintenance function

A warning signal is output to notify that maintenance is required when the air filter or condenser becomes clogged. If the thermistor fails (out of control), emergency operation is possible by selecting another operation mode. This function minimizes the factors of line stoppages.

The control panel has been revamped.

Data is now displayed in an easier-to-understand format with more digits space. The power consumption is also displayed.
