Double oil filters, also known as duplex oil filters, are specialised filtration units designed for use in industrial refrigeration systems, particularly those employing ammonia (NH₃) or CO₂. They continuously eliminate impurities from the compressor oil while ensuring uninterrupted operation during filter maintenance or replacement.

A double oil filter features two parallel filter housings linked by a changeover valve or a three-way valve. This innovative setup enables the system to alternate between filters without the need to shut down the refrigeration system, ensuring optimal efficiency.

The AURA EXZ is a sub-atmospheric back-pressure regulator specifically designed to provide adjustable relief for excess positive pressure in vacuum systems, which can occur due to pressure build-up or upstream sample injection. Featuring a proprietary hybrid spring system and an oversized dual-surface diaphragm, the AURA EXZ guarantees exceptional precision, stability, and repeatability in its performance. With multiple seat material options available, this regulator effectively eliminates any unwanted reactions with process media, allowing for accurate throttling of excess pressure and helping to maintain optimal process conditions. Each AURA EXZ regulator is meticulously assembled in a Class 100 cleanroom, complete with all necessary gauges, fittings, and valves. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to comprehensive flow and function tests to ensure long-term reliability, durability, and leak integrity, even in the most demanding environments worldwide. For applications that involve highly corrosive or aggressive substances, the AURA EXZ can be equipped with Dursan® LS inert coating technology, providing superior resistance to acidic and caustic media compared to traditional exotic alloys. This inert surface not only prevents moisture and media absorption but also ensures consistent performance in sensitive processes. With its precision control, advanced material options, and robust construction, the AURA EXZ is the ideal choice for accurate and reliable excess pressure control in sub-atmospheric applications.
