York Integral VSD Hydronic Pump Kit
The new JCI/York Chillers offered on KIG’s site are all from York’s “Stock Chiller Program” with one common set of options which have proven to satisfy over 90% of applications presented to us. These chillers, however, do NOT have internal water/glycol pumps onboard or included. We do offer chillers built-to-order with the hydronic pump package. When compared to providing your own pump with a stock chiller, the price adder for the hydronic pump package will seem very expensive. But, the hydronic pump package is a very sophisticated and well engineered offering including all items below. Many find the savings in field installation costs justify the adder. Lead times for such chillers can range from 10 to 18 weeks depending on model and backlog which often influences a decision. Contact KIG for more details.
