Published: 19. 10. 2026 - 9:00 Protect an entrance, heat a larger space or improve the distribution of warm air. TDC helps select SONNIGER equipment to suit the building, installation conditions and controls.

GUARD ONE: a compact solution for smaller entrances
A Plug & Play air curtain with integrated controls and a motion sensor for smaller shops, offices and service premises. The 1,100 mm long casing is 155 mm high and 281 mm deep. Select the unheated 100C or electrically heated 100E version for the application.
GUARD: standard air curtains
The GUARD range includes 100, 150 and 200 models with hydronic heating (W), electric heating (E) or no heat exchanger (C), in suitable AC and EC versions. Controllers, door contacts, sensors, BMS modules, valves and mounting accessories must match the exact unit.
GUARD PRO: larger industrial entrances
GUARD PRO 150 and 200 models are available in W, E and C configurations, with S3 or EC variants. The selected mounting arrangement, controller, door contact and accessories depend on the doorway geometry and operating conditions.
HEATER CONDENS and HEATER MIX
Hydronic unit heaters serve warehouses, workshops and other larger spaces. The CONDENS range includes CR ONE, CR1, CR2, CR3 and CR MAX models; HEATER MIX is a separate family. AC or EC versions and compatible controls are selected for the project. Nominal range figures do not replace a calculation at the actual water and air temperatures.
Cooling accessories include suitable condensate trays for HEATER CR and CR MAX. Cooling suitability, drainage and operating conditions must be confirmed for the selected version.
Send us the conditions, not just the model name
For an air curtain, send the doorway width and height, mounting position, opening frequency and heating supply. For a unit heater, send room dimensions, mounting height, heat load and water temperatures. We will help coordinate the equipment and accessories.
