Adsorption Filter Systems
While with the filter system CFH classic 100% of the loaded carbon will be changed at one time, the load capacity of the carbon will be used more efficient with the filter system CFH hightec. There, only the first half of the filter bed will be disposed, while the relatively unloaded second half of the filter bed will be changed to the first half. Only the second half of the filter bed will be filled with new carbon.
Any adsorption filter system type CFH will be designed according the special requirements of the single project.
Krantz cartridge filter system consists of multiple individual canisters in metal execution, assembled into a holding frame to fit standard dimension filter sections in air handling units. Krantz cartridge filters come factory ready for installation. No special tools are needed to replace a canister. The individual canister seals and holds in the frame due to its unique seal and bayonet-style clamping mechanism.
The gastight rectangular shut-off damper, type GD-R, surpasses by far the leak tightness requirements specified in DIN 25 496 (Ventilating components in nuclear facilities).
Krantz‘s gastight rectangular shut-off damper, type GD-R, guarantees a maximum of safety and reliability thanks to
The requirements on tightness as laid down in the German standard
DIN 25 496 – Ventilating components in nuclear facilities - are more than satisfied.
Several decades of experience gathered in the operation of shut-off damper systems in nuclear facilities and labs have decisively influenced the design and shape.
Quite a number of references from various locations of shut-off damper installation have proved the high level of perfection attained by this.
Krantz range of pressure relief dampers covers:
The Pressure Relief Damper Type KL-E is a design variant provided with control function which, as soon as then opening pressure is exceeded, keeps nearly constant the pressure in the ductwork, independent of the range of volume flow. When the pressure in the ductwork reduces to its normal range after the malfunction has been remedied, the damper closes automatically.
The Pressure Relief Damper Type KL-EM features a switching function. Independent of the range of volume flow of the outlet flow the damper blade gets fully opened when the opening pressure is exceeded. When the pressure in the ductwork falls below the opening pressure after the malfunction has been remedied, the damper normally remains open. In this state of operation the damper type KL-EM must be closed manually, whereas it closes automatically when the flow is interrupted, e. g. by disabling of the fan. Despite its smaller outside dimensions type
KL-EM is capable of removing flows at higher range of volume flow as compared with type KL-E.
They are installed e. g. often on the positive pressure side of parallel arranged ventilators and will prevent reverse airflows at a stop of one ventilator. When the ventilators are running the lamellae are open due to the airflow
Non return dampers are optimal if the pressure drop should be low with open lamellae and the leakage should be very small in closed position. Krantz is producing non return dampers since many years and these have been installed in HVAC systems with good success. Based on practical experience and many laboratory tests Krantz non return dampers have been optimized. The result is a non return damper with a very low pressure drop and especially small leakage rates.
According to the closing pressure an initial tension will be adjusted at an installed spring system. This initial tension ensures an open position of the damper regarding wind blasts and variation of pressure inside the duct system. In open position and case of installation outside of outer walls the damper also fulfils the functions of a rain protection grille.
PRDs can be used in almost any application where ventilation or exhaust air must be modulated. However, the following applications are examples where the superior capabilities of the PRD are evident:
Accessory and Miscellaneous
The portable leak testing device type LTD is for testing of the permissible leakage air flow e. g. according to DIN 25 496 “HVAC components in nuclear facilities” or KTA 3601 “HVAC systems in nuclear power plants” for:
in a measuring range from 0.01 to 1.5 l / min up to a theoretical test pressure of 5,000 Pa. The measuring devices integrated in the housing will be calibrated before assembly.
The Krantz heat sealing device provides ease of handling and guarantees optimum safety. The maintenance bag is gathered clamped tightly and heat sealed so that the contents of the maintenance bag and the inside of the filter housing be sealed and separated in one simple process.
The Krantz heat sealing device consists of the clamping device for the bag, heated element, transformer and a separating device.
The Krantz heat sealing device HS-D hightec combines
Krantz sealing device HS-D hightec is used in nuclear industry and safety laboratories for many years.
This ensures that the control is based on a closed loop. Typical true flow feedback air flow measurement applications are:

Advantages of Vortex shedding air flow measurement:
All HVAC components are placed in two containers. The allocation of the components to a supply air container and an exhaust air container will prevent any cross – contamination. We will deliver these containers as independent systems, i.e. completely installed and checked with all essential components for air delivery, air filtration and room pressure control.
Our desiccant dehumidifiers are well proven and used in the following
• Food industry (confectionery, meat processing, dairy, beer production)
• Drug manufacturing (tablets, ampoules, drug storage)
• Chemical industry (mineral fertilizer storage, transport)
• Sports facilities (ice arenas)
• Energy (equipment preservation with dry air)
• Products storage with close control of the humidity in the air
Our Desiccant dehumidifiers will help you to solve the problems that arise
due to increased moisture in the air which are corrosion, product damage,
product adhesion, mold and fungi growth on the surfaces.
Clean Air Solutions
Thermal exhaust air treatment
Catalytic incinerators for the cleaning of industrial exhaust air at low combustion chamber temperature. The catalysts are individually matched to the requirements. With the use of highly efficient plate heat exchangers, autothermic unit operation is possible even at low solvent concentrations.
Areas of application
Flexographic or gravure printing
Chemical and pharmaceutical industry
All kinds of painting and coating plants
Concentrator units combined with thermal oxidisers, regenerative thermal oxidisers or catalytic incinerators represent the most economical technology for cleaning large exhaust volume flows with low solvent load. In this process, a continuously rotating rotor made of hydrophobic zeolite adsorbs the organic pollutants. Afterwards, the adsorbed pollutants are desorbed with the help of a small hot air stream and are fed into a thermal exhaust air cleaning unit.
Areas of application
Painting and semiconductor industry, GRP industry
Thermal oxidisers with recuperative exhaust air pre-heating for the cleaning of industrial exhaust air with high concentrations of organic pollutants. The unit types INTEGRA and FLEXA feature a highly efficient internal heat usage. In combination with downstream heat recovery systems, they permit an economical unit operation with low additional fuel requirements.
Areas of application
Printing, coating, laminating and impregnating processes
Regenerative thermal oxidisers for the cleaning of industrial exhaust air using ceramic heat storage materials. The proven types from the REGETAR series guarantee economical unit operation Independent of the pollutant concentration, even for very large exhaust air flows. Due to the use of a regenerative ceramic heat store, autothermic operation is possible even at low solvent concentrations.
