Taking Gas Fired Premix Condensing Boilers to New Levels of Output
The Rendamax R3400 & R3600SB series of gas fired condensing boilers set bench marks for high output, combined with low weight, compact dimensions and low emissions. Up to 1895kW is obtainable from a single unit.
Manufactured using all stainless steel heat exchanger components; robustness and longevity is inherent in this series of boilers.
Modulating down firing premix burners with unique water cooling to the combustion system returns controllability with efficiency and clean burning. With a power range from nominally 660kW to 1.9MW and the possibility to use up to eight boilers in a cascade arrangement; the Rendamax R3400/R3600SB Boilers are ideally suitable for larger commercial heating applications such as Secondary Schools, Offices Blocks, Retail Centres, Hotels, Residential Blocks or Community Heating Projects.
Rendamax R3400
High output stainless steel premix gas fired condensing boilers. The R3400 is the premium boiler solution.
Product Features
Ultra high efficiency, fully condensing with ultra low emissions
The heat output is fully variable between 25% to 100%. This ensures the boiler output automatically matches the system demand, with optimum efficiencies of 100% nett being returned. With the use of a 100% Pre-mixed combustion process, flue emissions are kept very low at:
< 53 mg/kWh – NOx (30 ppm DAF)
< 19 mg/kWh – CO (15 ppm DAF)
Direct-on-boiler weather compensation
If required, the boiler can operate to give automatic weather variable flow temperature. This ensures optimum operating efficiencies by varying the flow temperature relative to the external weather conditions.
Comprehensive control panel (optional)
The boiler control panel includes user friendly controls, which manages the entire safety functions of the appliance, simple menu driven programming via a large LCD display, frost and summer standstill protection, and more.
Room sealed flue
As a special order, the Rendamax 3400 boilers covered in this brochure can be supplied to operate as a room sealed appliance, taking air for combustion (connection F1) directly from outside the building. The case of the boiler is under negative pressure giving adding safety.
Stainless Steel Heat Exchanger
The Rendamax 3400 range of boilers utilises a well proven Stainless Steel Heat Exchanger which is connected in sectional form, and has a water cooled Stainless Steel tubular burner.
Optional matched controls for optimum efficiency
A versatile range of matched controls are available to work in conjunction with the boilers and can provide not only room temperature control, but also independent heating and hot water time control with individual day programming.
Safety valve
The Rendamax 3400 range of boilers detailed in this brochure all come supplied with 3 Bar Safety Valve factory fitted as Standard.
Guarantee
The Stainless Steel heat exchanger carries a 5 year guarantee, all other components carry a 12 month guarantee against manufacturing or material defects.
