Best Practice Guidance for Refrigeration, Air Conditioning & Heat Pump Engineers Leak testing an HVAC or refrigeration system should always be carried out using oxygen-free nitrogen (OFN), suitable pressure testing equipment, and approved leak detection methods. Proper leak testing helps prevent refrigerant loss, improves reliability, supports F-Gas compliance, and reduces costly system failures. For refrigeration, […]

Analogue vs Digital Manifolds for Refrigeration, Air Conditioning & Heat Pump Engineers For refrigeration, air conditioning, and heat pump engineers, a reliable manifold gauge set is one of the most important tools in the van. Whether you’re commissioning a new split system, servicing commercial refrigeration equipment, pressure testing pipework, or diagnosing faults on a heat
