This system will include: Temperature Control Unit (226 kW cooling capacity, 150 kW heating capacity and a maximum operating temperature of 350°C) ### Chiller (350 kW cooling capacity) Design of the Temperature Control Unit and Chiller System, along with all necessary components for operation. Commissioning of the system. Installation of the system. This system is very similar to the operational HIVE test rig which has used this supplier for the last seven years and shares the same fundamental design concept, many similar components, the cooling system and operational principles. These specific nuances are currently only understood by ICS Cool Energy. This project is an extension of the organisation’s Induction-heating based HHF testing programme and there is a stakeholder requirement to ensure equipment is directly comparable, and compatible to the HIVE facility, including physical interfaces, control, and data acquisition (see approved TD-0012050-A: SHR-010, SHR-011, SHR-013). As a result another supplier would have to retrofit the HIVE test to match the proposed HHFTVF facility increasing the cost beyond what we have been quoted. The absence of this system poses a significant technical risk to the project, as it will result in certain key stakeholder requirements falling out of scope and lead to a diminished operational capability, such as the inability to accurately replicate the first wall environment as well as future use cases.
