Enhance the axial-flow, side-blowing hot-water-steam air curtain.

Compact model with a small cross-section, low noise level, and weak blocking performance; suitable for narrow openings. Designed for bilateral airflow, it is installed on both sides of the opening and operated with opposing airflows; the unit includes an on/off switch. Customizable machine height to match door height; the unit must be securely anchored to the floor and side walls before use. The housing is made of carbon steel with a white electrostatic powder coating; custom housing colors or stainless steel panels are available. The hot‑water version requires water at 70°C or higher, while the steam version requires steam at 0.4 MPa or less. Operating ambient temperatures must be above 5°C; during the heating season, continuous heat supply is required to prevent freezing and cracking of the internal heat exchanger.

Description

Model Name
RM19Z-C-S(Q) Side-Blow Series I

Main uses
For narrow openings no wider than 3 meters, install on both sides to prevent outdoor air from entering and to provide indoor heat supplementation.

Place of Use
For narrow openings where blocking performance is not critical and top-blowing units cannot be installed, supplemental heating is the primary approach.

Product Overview
Small-sized models feature compact cross-sectional dimensions, low noise levels, and limited blocking performance, making them suitable for narrow openings.
Designed for bilateral blowing, it is installed on both sides of the opening and operates with opposing airflow; the unit is equipped with an on/off switch.
Customize the machine height to match the door height; the machine must be securely anchored to the floor and side walls before use.
The enclosure is made of carbon steel with a white electrostatic powder coating; custom enclosure colors or stainless steel panels are available.
The hot-water type requires water at a temperature of 70°C or higher, while the steam type requires steam at a pressure of 0.4 MPa or lower.
The ambient temperature must be maintained above 5°C, and continuous heating is required during the heating season to prevent freezing and cracking of the internal heat exchanger.
