High flow and quiet pressure control, The Caleffi PresCal™ 535H pressure reducing valve is precision engineered to deliver accurate pressure regulation under varying pressure and draw conditions. Low internal pressure losses produce superior falloff performance enabling more flow capacity to fixtures. NSF/ANSI/CAN 61 compliance, superior 180°F temperature rating, anti-scale components and convenient cartridge design add to the many features of this versatile and dependable PRV. UV Outdoor protective cover included for non-freezing outdoor installations.Pressure reducing valves are devices which, when installed on water systems, reduce and stabilize the pressure of the water entering from the water supply main. This pressure, in general, is too high and variable for domestic systems to operate correctly.The 535H series pressure reducing valves, ideal for residential and commercial applications, feature a dial indicator with direct readout allowing easy pressure pre-adjustment. After installation, the valve will control at the pre-adjusted pressure setting.The valve is constructed of DZR low-lead forged brass and incorporates a unique noise reducing and high flow seat design, is easily serviced with a replaceable cartridge and has an integral stainless steel filter (35 mesh), suitable for water systems that may contain sediment and debris.The valve is ICC-ES certified to ASSE 1003, CSA B356, NSF/ANSI/CAN 61 (180°F/82°C Commercial Hot), NSF 372, low lead laws and listed by ICC-ES. It meets codes IPC, IRC, UPC and NPC for use in accordance with the US and Canadian plumbing codes. Plenum rated: compliant with the requirements of standard UL 2043, without the outdoor protective cover.

Insulated intermediate panel for connection with Mark Ceilfit radiant panels (insulated).

The Mark CEILFIT radiant panel creates a comfortable work and living environment through heating and cooling by convection and radiation. It is easy to regulate zones or rooms individually to ensure a pleasant surrounding. The Mark CEILFIT panels are compatible with grid type ceilings and can replace the standard tile without any additional work to the grid. The standard panels are available in common standard grid dimension, or as custom dimensions on request. This version is insulated with a mineral wool with an aluminium foil layer. Features - Easily installed in standard T-Grid ceiling - Cost efficient heating and cooling - RAL 9010 powder coated - Constructed of 0,7 steel sheet fused to copper tube - Copper tubing (10×0,4mm) can withstand pressure up to 6 bar - Easy to clean - Frees up floor and wall space - Rapid warm up times, due to low water content - Low pressure drop (operating pressures) - Low whole life costs – lack of moving parts - In accordance with NEN-EN 13964 regulation To support the weight of a fluid filled panel we strongly advise to add suspension wires from the panels to a structural part of the building or ceiling. The panels are accomodated with several holes to fix the supension brackets or cables. - Snelle opwarming, vanwege een geringe watervolume - Lage waterweerstand - Geen onderhoud - Volgens de NEN-EN 13964-norm Om het gewicht van een met vloeistof gevuld paneel te ondersteunen, raden we aan om de ophangdraden van de panelen aan het plafond te bevestigen. De panelen zijn voorzien van gaten om ophangbeugels of -kabels aan te bevestigen.

The INFRA AQUA ECO is a water-supplied radiant ceiling panel fitted with a glass wool insulation blanket as standard. This insulation blanket prevents heat from being radiated upwards. This appliance offers the option of heating without displacing air. In addition, heat reaches only the location where it is required. The short warming-up period and the lower room temperature can yield good energy savings. The panels are delivered in standard lengths of 4 or 6 metres. The panels may also be suspended in parallel with standard widths varying between 305 – 1.300 mm. The panel is supplied in white RAL 9010 as standard. Other RAL colours are available on request. Features Infra AQUA ECO - Simple installation / suspension - Low weight per metre - High heat emission - Galvanised finish for collectors and registers - Linking of panels by means of press couplings - Measured and approved in accordance with EN 14037 1-3 - Ball-resistant
