Wall-mounted air heater CALIS 331 - 27 kW - Industrial heating Sovelor

Hot Water Air Heater CALIS 331 - SOVELOR-DANTHERM
Maximum Heat Output: 27 kW

Description

The CALIS range air heaters are forced-air terminals designed for wall mounting or suspension installation. They connect to a dedicated hydraulic circuit, whether for hot water (heating mode) or chilled water (air conditioning mode). These units are suitable for heating, frost protection, or cooling various professional spaces.

Recommended Applications

Industrial premises and production workshops

Gyms and sports halls

Commercial spaces and office buildings

Exhibition halls and showrooms

Logistics platforms and warehouses

Garages and covered parking areas

Theaters and auditoriums

Reception and event venues

Areas prohibiting any open flame

Practical Advantages

Ceiling installation completely frees up floor space from any obstruction. The total absence of internal combustion eliminates the need for an exhaust flue, making these units particularly suitable for sensitive environments: logistics platforms, woodworking workshops, public establishments. Commissioning is limited to connection to the hydraulic network and compliant electrical supply.

Energy Performance

The CALIS range covers a power range from 7 to 80 kW depending on the heat transfer fluid temperature, combined with high air flow rates. This characteristic ensures rapid heating and effective frost protection. Power supply is via boiler, heat pump, refrigeration unit, or reversible heat pump. The F version includes condensate collection trays as well as anti-drip screens for dual-season use. Low-pressure coils combine an aluminum-copper exchanger in 2 or 3 rows depending on models, tested at 105°C under 8 bars.

Acoustic Comfort and Air Distribution

The reduced-speed helical fan ensures a contained noise level. Air flow is adjustable on two speeds. The horizontal blade adjustable discharge grille optimizes distribution. The double deflection grille option allows for refined lateral diffusion. A specific extended throw grille is available for wide-width premises.

Automation and Control

Fully autonomous and secure operation without permanent supervision. Individual or centralized control via switch, room thermostat, time programmer, or timer. Summer ventilation mode available. Optionally, a frequency converter allows fine adjustment of the discharge temperature.

Customization

Beyond standard configurations, SOVELOR-DANTHERM develops custom variants: air flow modulation, 1 to 3 row coils, ATEX versions, fresh air treatment with filtration boxes.
