KP/BB ECONOMIC air curtain

KP/BB ECONOMIC air curtain

Series of types of the curtains with two air streams “cold” and “hot”.
Curtains advantages:
- high operational efficiency
- lower exploitation costs
- lower thermal power of the heaters
- lower noise level of curtains operation

Air curtains are used to protect against uncontrolled external air inflow through the gates, building openings, in the doors of industrial plants, warehouse, retail pavilions etc.
Curtains are adapted to draw the air from the inside of the compartment.
They are intended for use in the gates of height 2,5-6m
Curtains can be placed above the gates or on the sides of the gates. It's possible to use several curtains placed next to each other.

Product description

Air stream in the curtains was divided into two streams: “cold” and hot”
“Cold” stream (1/3 of total air quantity) flows next to heater and then flows out with the higher velocity through the part of air blowing slot, when the “hot” stream (around 2/3 of total air quantity) flows through the heater and flows out through the rest  part of air blowing slot.
Air streams don't mix inside the curtain casing.
Curtains consists of:
- the casing made of galvanized steel sheets (with the possibility of painting) with the air blowing slot on the entire length  and with the partition limiting the air streams,
- water heater made of copper and aluminum,
- 2, 3 or 4 axial fans.
Curtains are manufactured in two versions: A and B, each of them in three sizes.
Each curtain size is made in several lengths.
Version B with the enlarged fans spacing and reduced air quantity is intended for the milder operational conditions of the curtains.

Working conditions


Curtains enable achieving the air velocity at the floor within the limits from 2,5 to 6m/s.
The water heaters are supplied with water with the temperature of 150OC or lower and the pressure of up to 1,5MPa.
