Brazed Packaged PHE with Thermal Store - 70°C - Plate Heat Exchanger with Thermal Store

Verified by manufacturer 4 months ago

BB10/300(70) (33 KW - 834 L/60 min PEAK)

Virdis Energy Ltd Variant:

VIRDIS ENERGY BB series of brazed plate heat exchanger (PHE), packaged, hot water and thermal stores.

0333 567 1121 Website

Application

Plate heat exchanger with thermal store suitable for:

  • Use in systems requiring high DHW outputs, fast vessel recovery with varying heat loads.
  • For larger applications a number of units may be installed in parallel.

Description

Plate heat exchanger with thermal store.


Thermal stores are available in a range of outputs from 33 kW to 152 kW (based on primary temperatures of 70℃).


The Brazed PHEs are coupled to thermal storage vessels with nominal capacities of 300, 500, 800 and 1000 litres. The vessels are manufactured from 316 grade stainless steel, fully insulated with rigid polyurethane foam - enclosed in a durable P.V.C. zip on cover. The Plate Heat Exchangers have very high outputs and low water content making them suitable for use in systems requiring high DHW outputs, fast vessel recovery with varying heat loads.


The thermal store allows for those high peaks which occur at various times, without the need for increased boiler capacity. All units are designed to operate up to a maximum primary operating temperature of 90°C and up to a maximum primary pressure of 8 barG.


All BB units consist of a brazed plate heat exchanger “kit” which has to be assembled on site by the installation team onto a stainless steel thermal storage vessel. This kit form is necessary for safe and efficient transport of the unit from factory to point of installation.


Features and benefits:

  • Thermal storage vessel manufactured from AISI 316 grade stainless steel.
  • Available in a range of thermal outputs (33 kW to 152 kW).
  • Primary temperature 70℃, cold feed temperature 10℃.
  • Storage vessel insulation - rigid polyurethane foam C.F.C. free.
  • Plate heat exchangers have very high outputs and low water content.
