Hughes EXP-MH-14KS/350 Immersion Heated 350 L Tank Safety Shower

The Hughes EXP-MH-14KS/350 stores 350 litres of water in a heated and insulated overhead tank, giving an emergency shower that works without a reliable mains supply and keeps its water in the tepid range in cold weather.

Tepid water from a stored 350 litre tank

The datasheet positions this unit as protection for worker safety whatever the weather. The immersion heater holds the tank water within 15 to 38 C, and the model is suitable for both hazardous and non-hazardous environments: the electrical equipment is listed for ATEX Zone 1 and 2, gas groups IIA and IIB, temperature class T3, with IIC available and non-flameproof models also offered.

The 350 litre tank is the smaller of the two heated sizes on the Hughes tank range and is the practical choice for a single operator station. Shower flow is a minimum of 76 litres per minute through a GRP and stainless steel shower rose, started by a red stainless steel panic bar or an optional foot panel, with an optional eye/face wash mounted inside or outside the frame.

Technical specifications

Cold-weather duty and the electrical supply

A heated tank solves the opposite problem to a hot-climate tank: water that would be too cold to stand under for 15 minutes. EN15154 asks for tepid water, and the ANSI summary notes that prolonged exposure to water below 16 C risks thermal shock and stops a casualty decontaminating for the full period. The heater is the reason to choose this model over an unheated tank where nights are cold.

Set the electrical design before ordering: the heater needs a 240 V single phase feed, or 110 V if specified, and a hazardous-area installation needs a certified supply route. The web product page quotes operation down to -10 C, whereas the datasheet gives -30 C only with trace tape on the valve assembly and eye wash line; this page follows the datasheet.

Options and what to confirm before ordering

Listed options include a GRP ladder platform, GRP panels, drain sump and grating, syphon dump valve, temperature gauge, level indicator, foot panel or treadle, lighting, audible and visual alarm, Hydroclenz tank preservative, a handheld shower, strip screens, ramps, barriers, hose reels and a deluge tester kit. Confirm the lowest site temperature, the hazardous area zone and gas group, the supply voltage and the position of the tank refill line. The datasheet does not print option part numbers, so options should be listed by name in the request.

How the Hughes EXP-MH-14KS/350 works

The tank holds 350 litres of water above the shower. An immersion heater keeps the water at a mild temperature. When the user pulls the panic bar, the valve opens and the water falls through the shower rose.
