Vertical Side-Blow Centrifugal Hot Air Curtain

A vertical heated air curtain with side discharge across an entrance.

Overview

The vertical side-blow centrifugal hot air curtain delivers heated air laterally across an opening from equipment positioned beside it. This arrangement provides an alternative where an overhead unit is difficult to install or where the entrance geometry favours a side-mounted discharge.

The catalogue’s RM-LC-S/Q arrangement uses a double-inlet centrifugal fan, a pressure chamber and a heating section. Air passes through the assembly and leaves through the outlet to form a heated curtain across the entrance.

Hot water or steam supplies the heating duty in the described series. Cabinet position, outlet length, available heat medium and the relationship between one or two side-mounted units are considered with the actual door opening.

PRODUCT DETAILS

Product Features

Vertical side-mounted arrangement

The unit is placed beside the entrance so the discharge moves laterally across the opening. The position is coordinated with door travel, clear passage width and structural support.

Double-inlet centrifugal fan

The catalogue describes a double-inlet fan as the air-moving source. Fan selection is matched to the required airflow and the resistance of the heating and discharge sections.

Pressure-chamber distribution

Air passes through a pressure chamber before leaving the outlet. This arrangement is intended to support a more even discharge along the air-curtain opening.

Hot-water or steam heating

The series uses a selected water or steam heat source. Thermal duty, connections and the appropriate heat-exchanger arrangement are confirmed against the site’s actual utility conditions.

Compact installation concept

The catalogue highlights a relatively compact form and straightforward installation. Clearance for services, protection of the equipment and access to the side cabinet remain part of the layout.

Accessible servicing

The arrangement is intended to allow routine maintenance of the fan, heating section and connections. Service space should remain available after guards, finishes or adjacent door components are installed.

Steam rating basis: entering air 15°C and steam gauge pressure 0.2 MPa; the catalogue states that paired curtains double the listed airflow, heat and condensate. Hot-water notes state entering water not below 15°C and water temperature difference 20–30°C, reproduced as printed. The source labels the LC-S quantity as condensate; it is shown here as “listed water quantity” pending confirmation. Thermal variants must be selected separately.

WHERE IT WORKS

Applications

Suitable for building and industrial entrances where a vertical heated air-curtain arrangement suits the opening and a compatible hot-water or steam supply is available. One-sided or paired layouts require selection for the particular doorway.

Provide opening dimensions, preferred unit positions, heat-source conditions and required air delivery. Paired equipment and heating capacity are selected for the complete opening, not inferred from one unit’s nominal figures.
