GAS LEAK DETECTION

F-Gas legislation requires gas detection for refrigerant plant stipulating a gas detector, sensor or monitor must be installed to detect gas leaks. Murco gas detectors provide trusted detection for installations requiring stand-alone refrigerant gas leak detection. Typical applications include: chiller rooms, supermarkets, brewing, industrial refrigeration, food storage/processing, walk-in freezers/boxes.

valves

T&D supply specialist valves including Tenant Valves, Thermostatic Mixing Valves, Automatic Water Shut Off Valves, Float Valves, Solenoid Valves and Pressure Reducing Valves – we work closely with consulting engineers and contractors specifying and selecting the optimum valve for the flow control application, including BREEAM, TMV3 and WRAS approved.

float valves – keraflo

Keraflo float valves deliver significant advantages compared to traditional ball-float valves – float valves with positive action and weighted key-shaped floats avoid dribble, reduce noise and allows full flow until the selected closed level is reached. Keralo Aylesbury float valves with WRAS Approval are specified throughout the domestic, commercial and industrial markets.

SOLENOID VALVES – asco

Direct operated valves are used in systems requiring low flow capacities. ASCO 2, 3 & 4 way solenoid valves available in normally closed, normally open and universal constructions provide flow control for water, air and steam in HVAC applications.

PRESSURE REDUCING VALVES – rwc

Pressure reducing valves (PRV’s) with WRAS Approval provide reliable flow control of domestic, commercial and industrial incoming water supply pressure eliminating inaccurate water pressures.

Thermostatic mixing valves – horne

HORNE TMVs (mixing valves) are healthcare sector approved, under the TMV3 Scheme, to NHS Model Engineering Specifications D 08 Thermostatic Mixing Valves (Healthcare Premises). For example, HORNE 15 TMV valve features an integral 7.8 L/min flow regulator for fitting at the mixed water outlet and, in the case of the H15 4th Connection TMV, for the outlet connecting to the cold water tap.

Thermostatic mixing valves (TMVs) mix hot and cold water supplies delivering temperature-controlled flow to building services – the hot water supply is typically around 60°C which is maintained at this temperature to prevent the growth of Legionella bacteria. Point of use TMVs for wash hand basins, bidets, baths and showers are specified throughout housing associations, healthcare, nursing, sheltered accommodation, education, sport and leisure, secure hospitals and prisons.

WRAS

WRAS product approvals contribute to the protection of public health by preventing contamination of public water supplies and encouraging the efficient use of water by promoting and facilitating compliance with the Water Supply (Water Fittings) Regulations.

WRAS replaced Water Byelaws with responsibility for water waste, misuse, contamination, excess consumption and erroneous measurement of water supplied – all WRAS approved materials must not effect water taste, colour or promote the growth of potentially harmful organisms. WRAS listing of a mixing valve demonstrate clearly and simply that the TMV complies with requirements of the Water Regulations when installed as specified by an installation Requirement Notes cited in the WRAS listing.

TMV3

TMV3 product approval is for the Healthcare and Commercial thermostatic sector using the NHS specification D 08 as a basis for the thermostatic mixing valves (TMV’s) performance testing.
