Safety door grid
For all fan doors with lever closures a swing-out hinged safety door grid is fitted to prevent accidental contact.
We use ventilators of different types:
- Centrifugal fan with belt drive
- Centrifugal fan with direct drive and a dual inlet
- Continuously operating wheel with direct drive
We use three-phase asynchronous motors with one, two and three speeds
- Energy-saving motors EFF1
- AC motors
Clamping device for belt driven motor / flat belt driven motor
The tension of the belt is via snowmobile or motor slide rails depending on the engine size. on request flat belts can also be used.
Base frames for motors and fans
Motor and fan are mounted together on a welded, galvanized frame and rubber buffer or spring dampers decoupled (depending on size) structure-borne noise.
Bag filter, cartridge filter (panel filter), activated carbon filters, and filter mat with cardboard or metal frame (tested according to VDI 6022).
Filter housing frame
With the universal holding - filter frame, the filter is clipped by spring snap closure. Therefore, the filter can be changed without tools. To reduce the total length of the unit, we can offer a pull-out variant. (Tested according to VDI 6022).
Easy maintenance due to high mechanical loading capacity, either fixed or extendable for cleaning, splitters with fiberglass cover, splitters with perforated cover, splitters with foil cover, all splitters with low profiled flow (tested according to VDI 6022).
All equipment components can be equipped with internal lighting. We install everything from simple basket lamps to the explosion-resistant fluorescent lamps - depending on requirements.
Air heater for hot water pumps, pipes and collectors made of copper, blades made of corrosion-resistant aluminum, frames made of galvanized sheet steel, or made of stainless steel. For air heaters for temperatures above 100 ° C, are collector pipes and blades made of galvanized steel. All heat exchangers are extendable. Other versions with frost protection thermostat.
Electrical heating coils heat the air. The embodiment is generally in several stages; the individual heating stages can be turned off or on as required.
Cooling coil and drop separator
Air cooler for cold pump water, air cooler for direct evaporator, pipes and collectors made of copper, blades made of corrosion-resistant aluminum, frames made of galvanized sheet steel or of stainless steel, heat exchangers and drop separators are extendable in a stainless steel tank inclined on all sides, thus a complete draining of the tank is guaranteed. To avoid the formation of condensation, the flow and return flow of the coolers are separated.
Plate heat exchanger:
The plate heat exchanger is easy to clean with its large access doors, further it has an inclined tank on all sides to the end, guaranteeing complete drainage of the tank. (also available according to VDI 6022)
Rotary heat exchangers
(also available according to VDI 6022)
Ventilation sound attenuators are supplied as pipe sound attenuators for round cable cross-sections and splitter attenuators for rectangular wire cross-sections.
Pipe sound attenuators:
Consists of a perforated inner tube covered with sound-absorbing insulation, non-combustible according to DIN 4102, covered with fleece, mounted in an outer protective tube.
Splitters sound attenuators:
Stable canal housing built in splitters with glass fiber, combined absorption and resonance sound attenuators of dual chamber design for ventilation systems, non-combustible according to DIN 4102, splitters with fiberglass cover, splitters with perforated cover, and splitters with foil cover. All splitters with low flow profile (tested according to VDI 6022).
According to customer requirements. If settings for volume flow, minimum attenuation or dimensions, the sound attenuators are factory-made.
Filter Extraction e.g.: smoke, odors, vapors and dusts ensure healthy air. The filter of the suction unit is adapted to meet your individual requirements. In this way you will receive the suitable suction unit for detailed-or volume suction for dust, smoke, oil mist, or gas. Our extensive range includes suction unit facilities and telescopes for welding fume extraction.
This easy-to-install ventilation valves are an affordable solution for small spaces, in which only small amounts of air is to be circulated.
Roof frame are needed for secure attachment of hoods for HVAC systems to the building. They are intended for mounting on flat roofs and sloping roof designs at up to 45 ° roof pitch. For the design and configuration of the components, the snow load zones (heights) and the wind loads of the respective application area are taken into account.
Roof frame are generally made of welded construction and can therefore absorb engine loads and wind loads and can be transferred to the roof structure. The fastening of the roof base to the roof structure is done via a circumferentially arranged pick up joke. The welded construction guarantees at the same time a proper water tight sealing of the roof base. Possible opening of roof structure so that air is easily carried out from the inner sides.
In addition, roof frames are also available in sound and heat insulated designs.
