CK Direct has launched the Recirc series of self-contained kitchen ventilation systems.
The manufacturer introduced the units to meet industry demand for recirculation, as more unusual and restricted spaces are being optimised by catering business owners.
Recirculating will allow such kitchen professionals to take advantage of existing spaces without the cost and practical implications that would apply to retrofitting permanent equipment like exhaust hood fans and ductwork, which filter airborne grease and smoke out into the atmosphere.
Hot, humid and grease-laden air is created whilst cooking and ReCirc extracts this air and recirculates it as clean air back into the kitchen. A backward curved centrifugal fan is mounted on a slide-out fan plate at the top of the unit, which draws contaminated grease-laden air from cooking appliances through four stages of filtration.
CK Direct’s units are designed to consider the environment and to eliminate major risks to the kitchen, such as ductwork fire hazards.
The multiple stages of filtration within the units remove grease, particulate, smoke and odour before re-introducing clean air to the kitchen – therefore the units need no direct duct connection to the atmosphere.
The four filtration stages for the standard CK Direct Recirc and Recirc ECO units start with a high-efficiency baffle-type grease filter unit mounted in front of the second set of filters. It then goes through a G4 pleated panel filter, HEPA filter and finally a carbon filter, which should effectively removing grease, particulate, smoke and odour in a safe manner.
CK Direct Recirc ESP uses a slightly different method, introducing the ESP stage after the baffle-type pre-filter. ESP or Electrostatic Precipitator is a process by which dust and other particles are removed by applying a high-voltage electrostatic charge and collecting the particles on charged plates.
Each Recirc unit’s technology and air purification system should make it appropriate for any commercial kitchen application and it is compact enough for tight openings and kitchens that have been fitted in the most unusual spaces.
The freestanding appliance is available in eight standard sizes, but units are also available within bespoke size requirements, including island canopies.
All units are fitted with single-phase fan motors for a canopy system sized up to 3,000mm and anything above that will be fitted with three-phase fan motors. The stages of filtration differentiate the three ReCirc model variations.
