The new Econo-Air gas-fired heating
and ventilation systems from Stokvis
are said to offer excellent indoor air
quality and optimum energy efficiency
for large buildings across a range of
industrial and commercial uses.

The Econo-Air range is highly
adaptable to meet user requirements.

Direct-fired units are available with
outputs from 15 to 900kW and
provide a fixed rate of heated fresh
air into the building space; indirect
fired Econo-Air models are available
with outputs from 30 and 1200kW.

A choice of air distribution heads
gives the option of ductless air
distribution, eliminating the need for
ductwork and de-stratification fan
units. Where ductwork is required,
systems can be configured to allow
for ductwork resistance of up to 2000
Pascals, making them suitable for use
with air induction systems.
