Product details
Variomat Giga hydraulic scheme
Hydraulic module in compact design for Variomat Giga pump-controlled pressurisation system. Suitable for and equipped for use in heat generator systems according to DIN EN 12828, DIN EN 12952, 12953 as well as for meeting the requirements of TRD 604 Sheet 2. and VDI 4708. Implementation of the functions, pressurisation and automatic make-up in closed heating and cooling circuits. Additional degassing of the system water with corresponding mains connection and operating parameters (70 °C) possible. Then self-regulating and optimised degassing control. All components are compactly arranged in a self-supporting, plastic coated tubular steel structure with foot plate so that they can be easily accessed and isolated. Pressurisation takes place using two low-noise vertical stainless steel high pressure centrifugal pumps with vibration decoupling in conjunction with two likewise, parallel arranged overflow lines. In detail these comprise a dirt trap connected in series and a dirt-insensitive motorised ball as an automatically adjustable overflow device. The entire overflow path is additionally protected in the event of minimum pressure undershooting by an additional solenoid valve in conjunction with a minimum pressure limiter integrated in the hydraulic scheme. Replenishment takes place via an electrically actuated valve. Control and operation of the Variomat Giga hydraulics takes place via an appropriate Variomat Giga control unit (separate product) installed in the hydraulic module.

7945724 - Commissioning Variomat Giga
Service description:
commissioning for a two-pump/compressor standard system in the Variomat Giga range by the customer service, comprising:
While it is entirely possible for customers to put a recently purchased system into service themselves, there are a number of reasons why commissioning by Reflex is a better idea.
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.
Services provided by Service are net! The price does not include any site waiting times or work arising from improper installation or improper condition.Programming the I/O and bus modules is not included in the scope of commissioning. Programming is charged separately according to time and effort.
commissioning for a two-pump/compressor standard system in the Variomat Giga range by the customer service, comprising:
- Adjustment of system to the operating parameters specified by the client,
- Checking the settings and operating parameters, and the system's performance and function in the overall system,
- All set values documented in a report.
- electrical and hydraulic connection of the control unit, the accessory components and filled supply system.
- The expansion vessels of the pressurisation station must not be filled with water.
- A sufficient supply of filling water must be provided.
While it is entirely possible for customers to put a recently purchased system into service themselves, there are a number of reasons why commissioning by Reflex is a better idea.
- Certainty that the system is set up for optimum operation
- Excluding of possible damage due to incorrect commissioning thus reliability and avoidance of time and costs for downtimes
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.
Services provided by Service are net! The price does not include any site waiting times or work arising from improper installation or improper condition.Programming the I/O and bus modules is not included in the scope of commissioning. Programming is charged separately according to time and effort.
