Pellet Heating Boilers

PZ 65 RL 65KW

Heating with renewable energies is the future and you will not only contribute to the environment, you also will reduce massively your annual energy cost.

The Biotech PZ35RL boiler is especially designed to deliver maximum energy to buildings such as:

– Family houses
– Holiday houses
– Small office buildings
– Workshops
– Small warehouses

The Biotech PZ65RL heating appliance has a performance range from 18.0 – 64.9 kW and is ideal to serve energy to buildings up to a surface of approximately 600 – 1’000m2. For bigger sized buildings up to about 3’000 m2 simply two or three PZ65RL appliances will be connected through cascade regulation and will optimally deliver energy as and when needed.

With a great nominal efficiency of above 94% the appliance is outstanding in its class and is leading in technology. Remote maintenance is made available through the capability of connecting the appliance with the internet and directly accessing the system from anywhere in the world.

BIOTECH PZ65RL – THE FULLY AUTOMATED PELLET HEATING APPLIANCE!

Consisting of:
– Electric connection: 230 VAC / 50Hz, 16 A
– Appliance body with efficient winding insulation
– Automatic ignition of pellets (hot air ignition system)
– Speed regulated induced draft and secondary air fan
– Lambda probe and air mass sensors (primary and secondary air)
– Temperature resistant tubular heat exchanger with automatic cleaning
