Stokvis Energy Systems products

ECONOMATIC REX & REX F boilers are high efficiency, non-condensing and of a traditional steel shell design with a three pass reverse flame combustion chamber. The REX is intended for use with gas, oil or dual fuel applications. The more efficient REX F is for gas only with a further option to stack in pairs on some models, known as a Dual. Outputs range from 70 to 6000kW Neither are intended for use where the ErP directive applies.

Gas fired, stainless steel, condensing, fully modulating, ultra low NOx premix burner. The R40 wall mounted boiler incorporates the latest high quality gas heating technology providing maximum efficiencies and minimum environmental impact. With six models ranging from 48 kW to142 kW, all small commercial requirements can be accommodated, along with larger commercial properties when modules are combined together.

Gas fired, stainless steel, semi-condensing, fully modulating, water cooled ultra low NOx pre mix gas fired boilers. The boilers are packed with features that are best in class and provide high output, extreme efficiency, reliability and ultra low harmful emissions. There are 6 models from 656kW to 1196kW.

Gas fired, stainless steel, condensing, fully modulating, water cooled ultra low NOx pre mix gas fired boilers. The boilers are packed with features that are best in class and provide high output, extreme efficiency, reliability and ultra low harmful emissions. There are 6 models from 572kW to 1043kW.

Gas fired, stainless steel, condensing, fully modulating ultra low NOx premix burner. The R600 series of boilers is packed with features that are best in class and provide high output, extreme efficiency, reliability and ultra low harmful emissions. Utilising the proven patented water cooled, down-firing, premix burner system coupled with a stainless steel heat exchanger assembly,R600 boilers have class leading NOx emissions. The R600 range includes 7 models with outputs from 142 to 545 kW.

Compact Brazed plate heat Exchangers are one of the most efficient ways to transfer heat. They are designed to provide unparalleled performance with very low life-cycle cost. Choosing brazed technology for heating or cooling projects will bring many benefits, including savings in space, energy, and maintenance. Our CBEs are extremely compact compared with other technologies. The footprint can be as little as one tenth that of a shell & tube heat exchanger. With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature approaches. The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance.

The Stokvis Econoplate E3i series of packaged plate heat exchangers are designed to operate with an LTHW primary supply for domestic hot water generation either instantaneously or coupled to a buffer vessel. They are available in 3 ranges covering a total of some 40+ units with outputs ranging from 51kW up to 1120kW (when fed with primary water at 80°C, secondary temperatures 10-60°C).
