ENVIGOR COMPACT DHW PLATE LOADING KIT (UP TO 12kW)
The CE520 Compact Plate Loading Kit provides a simple and cost-effective way to upgrade an existing direct or indirect hot water cylinder for use with heat pump systems up to 12kW, without replacing the existing cylinder.
Supplied fully assembled and pressure tested, the CE520 is built around a SWEP E5THx20 brazed plate heat exchanger with insulation jacket and a Wilo Star-Z NOVA A secondary circulation pump with integrated check valve.
The kit also includes isolation valves, a manual air vent and a drain-off valve, all housed within a compact insulated enclosure measuring approximately 424mm × 410mm × 240mm. Its pre-assembled design helps reduce installation time while providing a neat, space-saving solution for domestic hot water generation.

Technical Performance
The table below provides the approximate pressure drop across the SWEP E5THx20 plate heat exchanger at varying heat duties.
| Duty (kW) | Pressure Drop - Side 1 (kPa) | Pressure Drop - Side 2 (kPa) |
| 4 | 3.09 | 0.023 |
| 6 | 6.69 | 0.107 |
| 8 | 11.58 | 0.186 |
| 10 | 17.77 | 0.286 |
| 12 | 25.29 | 0.405 |
Pressure-drop values are approximate and are provided as a guide for system design. For more detailed information, please view the CE520 Installation Manual.
