Our industry-leading Econoplate packaged plate heat exchangers are available in various configurations, with over 250 models to choose from. Due to the flexibility of Econoplate heat exchangers, they are the perfect solution for almost any application, including steam to water, domestic hot water service (DHWS), swimming pool heating, low temperature hot water (LTHW), and even complex process heating. Econoplate units are designed to transfer heat from one medium to another, only requiring the two fluids to make a single pass through the heat exchanger. This method is simple, efficient and delivers proven results. Plate heat exchangers have low water content and low thermal inertia, meaning they’re ideal for use in systems with varying heat loads. Econoplate units are supplied packaged with – when needed – controls, primary pump (single or twin-head), secondary pump and/or a 2, 3 or 4 port motorised control valve fitted to the primary circuit.
Ideal for environments where hot water demand varies and high peak flow rates occur often, this powerful combination unit meets peak demand with the instantaneous plate heat exchanger output, storing volume within the buffer vessel for efficiency and speed. Coming with a compact brazed heat exchanger, thermal store, pump(s) and controls, the series is available in a range of outputs. The models range from 56kW to 231kW (based on a primary temperature of 80°C) and 33kW to 152kW (based on primary temperatures of 70°C). The heat exchangers are then coupled to thermal storage vessels with nominal capacities of 300 to 1000 litres.
The H series Econoplates are designed to provide the interface between a central or district heating scheme and individual properties, requiring heating and/or hot water. At the heart of each unit are the stainless steel brazed plate heat exchanger(s) which are packaged with the necessary equipment to control your heating and or instantaneous hot water requirements. The unit types are essentially H1 (Single Plate) or H2 (Twin Plate) with 3 models for each type.
Our heat exchangers can be built for a wide range of specifications due to their modular design. With a choice of frames, plates, connections and plate types, these heat exchangers have the flexibility to suit almost any requirement. BPHEs can easily be disassembled for ease of inspection, maintenance or even expansion by adding plates. Due to the small dimensions of a BPHE, they can be transported, installed and accessed for maintenance more easily than most alternative heat transfer products. Overall, our bare plate heat exchangers offer an efficient, cost effective solution, in a compact, easy to transport and install package.
CBEs are a sealed unit with no gaskets, eliminating the risk of leaks. With no need for gaskets or supporting equipment, around 95% of the material is used for heat transfer. Thanks to highly turbulent flows, our CBEs are largely self-cleaning, making Cleaning in Place (CIP) without disassembly possible, even in applications with a high risk of fouling or scaling. With their robust construction, stable thermal and hydraulic performance and also minimal maintenance, the Stokvis CBE is the perfect solution for heat transfer.
ECONOPRESS enclosed pressurisation units are used for maintaining pressure in sealed heating or chilled water systems; automatically pumping water into systems to maintain initial ‘cold fill’ pressure.
The Stokvis Econoboost units are compact cold water booster sets designed to meet today’s need for reliable, high performance equipment with modest capital outlay and low running costs.
Stokvis Heatpak is a unique standalone bespoke packaged plant room, tailored to the site-specific requirements offering the practicality and performance of a standard packaged plant room whilst overcoming the typical difficulties encountered with this type of project. Incorporating high-efficiency Stokvis boilers and the Stokvis Econoplate, the Heatpak provides a fully modulated, high efficiency heating and hot water system, dramatically reducing running costs. Heatpaks can be provided with boilers, plate heat exchangers, pressure sets, booster sets, pipework, insulation, valves, flues, controls and power, all in six to eight weeks. On-site labour is also kept to a minimum which dramatically reduces downtime on site. Due to the low weight of Stokvis boilers, Heatpaks can be installed on roofs and alongside buildings, making it an ideal choice for decentralisation projects.

Stokvis boiler package keeps pace with phased conversion project
The Econoplate from Stokvis Energy Systems
The specialist contractor undertaking a major conversion project within a former office property in Leicester has continued a strong working relationship with Stokvis Energy Systems for the supply of its boilers, plate heat exchangers and other equipment in creating high quality apartments.
Trail Systems Ltd, headed by Patryk Halczak, is reconfiguring the six-storey Highcross House, located close to Leicester city centre, converting the former insurance building into 140 two- and three-bedroom homes. While the structure has been strengthened to take an additional two floors that are still awaiting planning consent, a phased programme has seen the existing floors divided up using modern partitioning systems. With the basement plant room refurbished, the trio of R602 boilers and two C3A Econoplate plate heat exchangers have been ramped up as phases of flats have been handed over for occupation.
Patryk Halczak commented, “My task was to deliver reliable solutions for the conversion project, and I know that each contract we have carried out with Stokvis has been absolutely successful – there have been zero issues over a period of many years.
“In the case of Highcross House, the boilers and other systems were commissioned more than six months ago, and have coped without any problem, despite being disturbed each time another floor or zone has been ready for connection. The building is now some 80% occupied with residents moving in on the fourth floor before the end of the year. Meanwhile, the boilers, plate heat exchangers and other systems have all been sized ready to serve the two additional floors when permission is given for their construction. These are high specification apartments and they are proving very popular with tenants.”
The R600 EVOLUTION series offers specifiers excellent economy and performance with compact dimensions, making them the ideal ‘go anywhere’ solution for retrofit projects. At Highcross House, they wheeled into position on a plinth, before being connected up to an Econopress unit to provide sufficient pressure to circulate primary water throughout the building.
The pair of C3Ai330+OR Econoplates were chosen for their compatibility with the R600 series boilers, helping them stay in condensing mode for longer as 700 flow and 500 centigrade return temperatures are targeted. A Stokvis Econoboost unit was also installed to circulate hot and cold water to kitchens and bathrooms throughout the building.
Amongst the other conversion projects around the country where Stokvis Energy Systems has provided Trail Systems with fully compatible heating and hot water services was Unity House in Luton, as well as a development called Wesley House.
