Panasonic Certified Quality

Panasonic does not compromise on product quality, safety or durability, in order to provide the ultimate comfort when you need it most.

Class A pump

Units can be equipped with an efficient pump. A wide range of single and double pump, plus pump drive option is available.

Axial AC

The microprocessor control automatically adjusts the fan speed as a function of the operating conditions.

BP heat exchanger

Very compact & long durability of SWEP Braze Plate Heat Exchanger.
Unique design for the size 140 - 210 improving frost protection and efficiency.
Model type supplied may vary.

Simple user friendly control

In addition to basic control functions…
· Intelligent logic control for inlet water temperature
· Night setback operation to reduce electrical consumption and noise
· Automatic test operation at the push of a button

Energy recovery

The “Desuperheater” option consists of a stainless-steel brazed plate heat exchanger which is mounted in series between the compressors and the air-cooled condenser. It can supply hot water up to 50°C free-of-charge while operating in the cooling mode, thanks to the partial recovery of condensation heat that would otherwise be rejected to the external heat source.

The unit’s efficiency is increased as condensing pressure can be reduced due to air cooled condenser becoming oversized.

* Available on special order only.
