Centrifugal side-blowing hot water steam type air curtain

Large models have large cross-sectional dimensions and good blocking effects, suitable for large venues with wide openings; Designed for double-sided blowing. If the installation location is limited and single-sided blowing is used, the machine model needs to be increased; Customized machine height, the same height as the door. The machine needs to be fixed to the ground and side walls before use; The shell is made of carbon steel plate with electrostatic spraying in white. The shell color or stainless steel panel can be customized; The ambient temperature is required to be above 5℃. Continuous heating is required during the heating season to prevent the internal heat exchanger from cracking; Hot water type requires the use of hot water above 70℃, and steam type requires the use of steam below 0.4MPa; With or without zone control. The latter requires an additional control box to operate the machine.

Product Introduction
Large model, large cross-sectional size, good blocking effect, suitable for large venues with wide openings;
Designed for double-sided blowing, if the installation location is limited and single-sided blowing is used, the machine model needs to be increased;
Customized machine height, the same height as the door, the machine needs to be fixed to the ground and side walls before use;
The shell is made of electrostatic spray-painted white carbon steel plate, and the shell color or stainless steel panel can be customized;
The ambient temperature is required to be above 5℃, and continuous heating is required during the heating season to prevent the internal heat exchanger from cracking;
The hot water type requires the use of hot water above 70℃, and the steam type requires the use of steam below 0.4MPa;
With or without zone control, the latter requires an additional control box to control the machine.
Classification by fan model:
RM20L-C-S(Q): Low noise, suitable for narrow openings and quiet commercial places;
RM23L-C-S(Q): Suitable for main entrances of commercial places, vehicle entrances and exits of factory buildings and warehouses;
RM25L-C-S(Q): Slightly higher noise, good blocking effect, suitable for wide openings in factories and mines;
RM28L-C-S(Q): High noise, high air pressure, suitable for extra-wide openings in factory buildings and warehouses.
Classification by heating range:
Energy-saving type: Hot air is blown for heating below 2 meters in height, and natural wind is blown to seal the door above 2 meters;
Standard type: Hot air is blown at the entire height, large heating capacity, suitable for places requiring a large amount of supplementary heating.
