Cooling

Our efforts to modify the cooling system were complicated by the fact that the right kind of valve (a 3-way servo valve with differential thermostatic control and adjustable set point) we needed was not easy to get within the specifications we had. The design was modified, no longer using the cooling water for the cooling of the FIES building, but purchasing a separate (small) cooling unit for the FIES building. This removes that need for the 3-way valve, making the overall design simpler (and likely more reliable) while the overall cost is basically the same.
