What is Posi-Stopโ„ข? Caleffi is rolling out a union seal design for a consistent and superior seal over the broad range of connections encountered in plumbing and hydronic applications. This versatile system uses an EPDM O-ring, in place of a fiber gasket. When the installer tightens the union nut, an O-ring seal compresses to a controlled value by way of a positive metal-to-metal stop. How do you know if it is tight enough? It stops spinning. No guesswork, enjoy perfect compression every time!

How maximizing the efficiency of heat pump systems? Today, heat pumps are changing the hydraulic heating and domestic water system sector from a green perspective. We have always been great supporters of renewable energy sources and, as such, we have developed a full range of products to ensure the correct operation, efficiency and safety of the new heating and cooling systems. - THE HYDRAULIC SEPARATOR In systems which anticipate the use of a booster pump, we suggest separating the primary and secondary circuits using a hydraulic separator. This is to avoid interference between these circuits due to variations in the flow rates and head generated by the circulation pumps. Hydraulic separator for heating systems: https://www.caleffi.com/international/en-int/catalogue/hydraulic-separator-heating-systems-manifolds-550-series-dn-32-550305 - THE DIRT SEPARATOR STRAINER As far as water treatment is concerned, a heat pump system behaves like a traditional boiler system and is subject to the same legal requirements (in Italy, the Minimum Requirements Decree of 2015). Keeping the water quality suitable for constant circulation helps to achieve an energy saving of 8 % for the system. How? By installing a dirt separator or a magnetic dirt separator strainer and proceeding with compulsory chemical conditioning using the specified additives. CALEFFI XF: https://www.caleffi.com/international/en-int/products/search?query=xf - MOTORISED DIVERTER VALVES These allow management of the flow between the air conditioning system (heating and air conditioning) and the domestic water preparation system. - THE INSTRUMENT HOLDER For heating systems with an air vent, composite safety relief valve and pressure gauge. INSTRUMENT HOLDER 305 SERIES: https://www.caleffi.com/international/en-int/catalogue/instrument-holder-composite-material-air-vent-safety-relief-valve-composite-material-and - THE ANTIFREEZE VALVE This allows the circuit medium to be drained when its temperature reaches an average value of 3 ยฐC, thereby preventing ice from forming in the circuit of a system with a heat pump and avoiding potential damage to the machine and the pipes.

You'll learn: โ†’ How to apply the systematic approach to troubleshooting from Part 1. โ†’ Several compromised performance symptoms and causes. โ†’ Design modifications to prevent issues. โ†’ Corrective actions in existing systems. Siegenthaler is a seasoned industry leader and passionate teacher, eager to share his over 40 yearsโ€™ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.
