Featured Products

Ultrabox 210kW to 1125kW

Recently introduced, the Ultrabox range of gas-fired condensing boilers is available in capacities from 210kW to 1125kW, with cascade capabilities for up to 16 units. Ultrabox boilers feature a fuel engineering related efficiency of up to 110% and 8:1 turndown capability and are suitable for a wide range of flow rates with low pressure drop. NOx levels are low, at 34mg/kWh.

Zero side clearance means the installed footprint is up to 30% smaller than competing models, enabling optimum use of plant room space. The smallest model in the range has a footprint of just 0.72m2.

All models are suitable with natural gas or LPG.

Superbox 160kW to 1,060kW

New Superbox commercial gas condensing boilers with stainless steel heat exchangers deliver up to 106.4% net efficiencies with Class 5 NOx levels, backed by a five-year warranty.

Superbox boilers are available with heat outputs from 160kW to 1,060kW and feature pre-mix combustion technology, as well as a high modulation ratio to ensure that high efficiency is maintained at variable heat loads. Superbox boilers can also be combined in cascades of up to 16 boilers for maximum flexibility.

For even greater flexibility, the integral master control panel provides control of up to three different zones. Superbox boilers are also designed for ease of installation and maintenance.

Wallcon 115kW to 160kW

MHG’s new Low NOx (Class 5) Wallcon wall-mounted gas-fired condensing boilers are available in 115kW, 125kW and 160kW capacities, with the ability to combine up to 16 units in cascade configuration. Further flexibility is provided by a fully modulating pre-mix burner with 4:1 turndown capability for the 115kW model, and 7:1 for other models.

They are available with matched mounting frames and cascade hydraulics including low loss headers or matched system separation plate heat exchangers. The range features built-in frost protection and time control, with direct BMS connectivity and remote monitoring options.

All models are suitable with natural gas or LPG.

ProCon HTP 150kW & 225kW

ProCon HTP range of gas-fired condensing boilers feature integral plate heat exchangers to separate the boiler from the distribution system. As such, they are ideal for retrofitting high-efficiency (98.1% gross seasonal efficiency) boilers to existing systems, as required for boilers below 400kW under current regulations.

There are two models; the ProCon HTP 150 comprising 2 x 75kW modules and the ProCon HTP 225 with 3 x 75kW modules. These can be combined in cascade configuration to deliver higher capacities, using fully modulating burners and integral controls to provide efficient response to varying heat loads.

The internal system separating plate heat exchanger allows the ProCon HTP to be applied to any system with operating pressures up to 10 bar without the risk that the existing distribution system will impair boiler performance.
