Indirect Water Heaters

    • Dual coil indirect calorifier for a wide range of applications
    • 37 – 80 kW output
    • 382 – 1007 liter capacity

    • Single-wall spiral heat exchanger
    • PermaGlas Ultra Coat second-generation glass coating technology prevents corrosion
    • Insulated ring base for easy installation
    • Insulated access cover for comprehensive waterside maintenance
    • Replaceable magnesium anode
    • Options:
      – Flexible magnesium anode for installation in confined areas
      – Powered anode for reduced maintenance requirements
      – Temperature and pressure valve with stainless steel spring set to 95°C and a maximum water pressure of (7 bar) 700 kPa
      – Analogue temperature gauge (0-120°C)
      – Destratification pump kit
      – Electric element heat packs (3 – 36 kW). Electric back-up heating up to 7.5 kW

    Sample specification

    The tanks shall be A. O. Smith ITS series industrial indirect hot water storage calorifier, model n0 ITS_xxxx (400-1000L) or an approved equal. The tank shall be for vertical installation. Vessel shall be constructed to European Pressure Directive for minimum 7 bar working pressure. Vessel shall be glass-lined, have one to three sacrificial magnesium anodes for additional corrosion protection. Entire vessel shall be insulated with 70-100 mm NEODUL insulation with ABS cladding. Heat loss will meet ErP standards. A combined temperature and pressure relief valve will be factory supplied. Two factory-installed boiler water/solar heat exchangers will meet the heating requirement as specified for this project. The tank will have the option to install a back-up electric element up to 7.5 kW.
