Applications

Heat Pump Fans

In short: 15 series (80 models) cover 300–10,000 m³/h, up to 815 Pa static pressure for Heat Pump Fans.

A heat pump spends most of its life at part load and in bad weather, so the fan must stay efficient at low speed and keep running through rain, snow and defrost. Our axial and centrifugal ranges are specified for exactly that duty.

Families: 15
Models: 80
Airflow: 300–10,000 m³/h
Motor types: AC / DC / EC

Typical applications

Outdoor units of residential and commercial heat pumps.
Air-to-water monobloc and split systems.
DHW heat pumps and pool heaters.
Hybrid and multi-source heating plants.

How to choose

Low-ambient heating duty decides the fan: check airflow derating at −15 °C and choose a motor whose speed reserve still meets the design point after defrost cycles.

Industry criteria, series picks and evidence

Heat-pump fans see wide ambient ranges, defrost cycles and outdoor noise limits; the fan curve and control mode matter more than the nominal airflow.

Criterion	Typical value	Why it drives the selection
Ambient range	−20 °C to +45 °C	Outdoor unit envelope
Static pressure	0–150 Pa axial, up to 600 Pa ducted	Ducted vs free-blow outdoor units
Control	0-10V/PWM	Speed follows compressor stage
Noise	night-mode setback	Speed reduction at defined hours

Recommended series
