IT - 1500/2000/2500/3000

Indirect water heater (calorifi er) for a wide range of applications

• Single-wall spiral heat exchanger • PermaGlas Ultra Coat

second-generation glass coating technology prevents corrosion

• IT 300: Three adjustable legs facilitate easy installation

• IT 400-1000: Insulated ring base • Insulated access cover for
comprehensive waterside maintenance • Replaceable magnesium
anode • Options: Flexible magnesium anode for installation in
confi ned 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

• Analogue temperature gauge (0-120 °C) • Electric element heat
packs (3 - 36 kW) • Optional ancillaries: unvented kits

• Destratifi cation pump kit
