Automatic air separator - 5/4" IVAR.DISCAL 551

Product detailed description

Automatic air separators are essential in closed heating systems to ensure efficient operation by removing entrained air. These devices are commonly installed in residential, commercial and industrial buildings where heating systems are subject to thermal expansion and contraction. Installers and service technicians encounter these units in central heating systems, underfloor heating circuits and hot water systems. The presence of air in the system can lead to reduced heat transfer, increased noise and potential damage to components. An automatic air separator helps maintain system performance by continuously removing air without manual intervention.

Correct selection and installation of an automatic air separator are crucial for system efficiency. The device must be sized according to the system's flow rate and air content. It should be positioned at the highest point of the circuit to allow air to accumulate and be expelled effectively. The separator must also be compatible with the system's operating conditions, including temperature and pressure limits.

The operating temperature limit of +110°C and nominal pressure rating of PN 10 are key factors in determining the suitability of this separator for a given application. These parameters ensure the device can handle typical heating system conditions, including thermal expansion and pressure fluctuations. The CW617N brass construction provides resistance to corrosion and mechanical stress, making it suitable for long-term use in closed heating systems.Installation and connection The IVAR automatic air separator is connected using a 5/4 inch thread, which must be matched with the corresponding pipe or fitting in the system. Installers should ensure the connection is clean and free from debris to prevent leaks. The separator should be mounted vertically, with the air vent positioned at the top. A common mistake is incorrect orientation, which can prevent air from being expelled properly. It is also important to verify that the system's pressure and temperature conditions do not exceed the device's specifications. After installation, the system should be tested for leaks and proper air removal function.Compatibility and accessories This air separator is compatible with standard heating system components such as circulation pumps, expansion vessels and heat emitters. It is typically used in conjunction with pressure relief valves and temperature sensors to maintain system safety. No additional accessories are required for standard installation. Related products include other IVAR air separation units and system monitoring devices.Technical background for designers The automatic air separator operates by allowing air to rise to the top of the device, where it is expelled through a built-in valve. The CW617N brass body provides good thermal conductivity and resistance to corrosion, while the stainless steel internal components ensure durability in wet environments. The device is designed to integrate seamlessly into closed heating systems, where it continuously removes air without the need for manual intervention. The efficiency of the separator is influenced by the system's flow rate, the amount of air present and the positioning within the circuit.Service and operation This air separator requires minimal maintenance due to its automatic operation. However, periodic checks should be carried out to ensure the air vent is functioning correctly and there are no blockages. The device should be inspected for signs of wear or corrosion, particularly at the connection points. If the system experiences unusual noise or reduced efficiency, the separator should be checked for proper air removal function. No scheduled service intervals are specified in the technical data.Frequently asked questions

Can the IVAR automatic air separator be used in hot water systems?
Yes, the device is suitable for hot water systems operating up to +110°C and PN 10 pressure. It is commonly used in central heating and domestic hot water circuits.

Is the 5/4 inch connection compatible with standard pipe fittings?
Yes, the 5/4 inch thread is a standard size used in heating systems and is compatible with corresponding pipe fittings and valves.

Can the separator be installed horizontally?
No, the device must be installed vertically to allow air to rise to the top and be expelled through the vent. Horizontal installation can prevent proper air removal and reduce efficiency.

What materials are used in the construction of the separator?
The body is made from CW617N brass, which provides resistance to corrosion and mechanical stress. The internal components are made from stainless steel to ensure durability in wet environments.
