Powerful, economical, compact
Gas condensing series R600 R3600 / 3400 are characterized by high heat output, compactness, low fuel consumption and low NOx emissions. The boilers are ideal both for renovation, and for new buildings. The long assembly times belong to the past: the devices are supplied from the factory, already equipped with premixing burner and accessories perfectly Integrated. What’s more, all the components are already preset and tested.
The larger the volume of water, the slower is the temperature adjustment
The big conventional boilers do not require either hydraulic separator or pump for the primary circuit. However, they have the follwing disadvantages: the heating circuit pumps must be bigger, therefore they consume more energy. It’s often needed an open collector that has the same function of an hydraulic separator. Due to a big amount of water contained in the circuit, the thermal inertia can bring to very slow temperature adjustment, as well lower efficiency.
Ultra-modern technology with low consumption
The operating costs of R600 and R3600 / 3400 series are up to 15% lower than those of conventional heating systems. Thanks to the the 1:6 modulation ratio, the power is perfectly adjusted according to the exact heat demand. As a consequence, the most comfortable heating is got, and the lowest usage of the burner is got thanks to reduced number of on-off cycles. A further advantage of R600 / R3600 / 3400 series: the advanced management with load regulation and flame control that allows the adding of more boilers in the cascade. Even the most complex buildings can be managed in an easy and convenient way.
Digital control for maximum comfort of use
The fully electronic climate control allows to manage up to two independent heating circuits with simplicity and extreme comfort. The adding of modules allows additional extension up to 16 heating ciruits. The regulation effectively oversees all the system functions and the parameters set can be displayed / modified from the digital display.
The most efficient solution: separation between primary and heating circuit
RENDAMAX has two adjustable flow rates made independent with a plate heat exchanger or hydraulic separator between the boiler and heating circuit. In this way, the volume of water in the boiler circuit is reduced to the minimum. The advantages:
• More effective modulation
The minimum volume of water in the boiler allows a rapid heat transmission and the boilers promptly react to the changes of the thermal requirements. Standing losses are reduced to the minimum.
• Higher efficiency
The R600 / R3600 / 3400 series are designed for high temperature differences in order to transmit a lot of energy to a reduced water volume. Moreover, the low temperature return ensures an optimum exploitation of condenastion heat.
• Reduced weight
The minimum water volume brings further advantage wherever it’s needed a reduced weight boiler (for example in the under-roof room).
• Low operation consumption
The R600 / R3600 / 3400 series have a very low electricity consumption, thanks to the little amount of water contained in the boiler circuit, that as a consequence requires smaller pump.
• Plate modulation burners with low-NOx and with water cooling; for low emissions with all boilers in the range.
• Low water contents
• Low operating costs thanks to burner modulated operation. Modulation from 30 % to 100%
• The large modulation range delivers long operating time of burner without heating unnecessary masses or high water quantities.
- Minimum energy losses and start-up emissions.
- Less burner start-ups = lower part wear
• High heat transfer and condensing
- Stainless steel 3-level heat exchanger
- Counter-current principle between boiler water and flue gas
- No low limit of return temperature
• Noiseless operation: 40- 58 dB (A). No insulation headphones necessary
• Minimum overall space thanks to compact design.
• Simple and safe use thanks to completely electronic climatic control; max. 14 heating circuits (optional).
