GL Hot Water Cylinders

The Adveco GL hot water cylinders are for vented or unvented DHW applications. Available in three ranges – GLE, GLC and GLT – and offering a wide range of sizes and configurations, GL addresses the bespoke needs of commercial hot water projects including direct electric heating, buffer storage, indirect heating & preheat.

The GL family of hot water cylinders are tough enough to deal with water conditions typically encountered across the UK, presenting building projects with a versatile choice of vessels to cost-effectively meet the demands of commercial hot water applications.

Constructed from a carbon steel shell with a high-quality enamelled inorganic lining (200-1000L) or blue epoxy powder coat enamel lining (1500-5000L) to prevent corrosion, these tanks are suitable for use in systems with maximum working pressure up to 10 bar and temperatures up to 85°C.

Features & Key Technologies

Options

Adveco GLC
With a single fixed indirect heating coil, the Adveco GLC range of calorifiers is designed to serve as indirect water heaters or preheat vessels. Available in 200 to 3000 litres capacities, the Adveco GLC features a single fixed indirect heating coil at low level and can also accept a 180mm 3-36kW electric immersion. The coil has a maximum working pressure/temperature of 12 bar / 110°C.

Adveco GLE
Available in a range of sizes from 200 to 5000L, the Adveco GLE is designed to serve as buffer vessel or electric water heater. Compatible with a wide range of direct electric immersion heater options available from Adveco, the GLE supports duty immersions from 3 to 36 kW, as well as secondary supplementary immersions from 3 to 6 kW for additional heating, or as backup to ensure continuity of service from a single unit.

Adveco GLT
The Adveco GLT range of calorifiers is designed to serve as indirect water heaters. The tanks, available in 200 to 3000 litres capacities incorporate two fixed indirect heating coils, one each at low and high level, designed for use with two separate heat sources.

All vessels also include a cleanout flange, a magnesium sacrificial anode (pre-fitted in 300-1000L variants), and a temperature gauge as standard (pre-fitted in tanks up to 1000L). They include a tough PVC jacket enclosing rigid high-density polyurethane foam or removeable polyester fibre insulation. The jackets and insulation are pre-fitted for tanks up to 1000L.

The Adveco GL range of tanks carry both WRAS and Kiwa’s KUKreg4 certification of product compliance with the water supply (water fittings) regulations for England, Scotland, and NI.
