Standard Datasheet [User Manual](/products/liquid-cooling-systems/nextreme-recirculating-chillers/VRC1200-A1-20-BT1/user-manual) MFG Part Number 387008451 # VRC1200-A1-20-BT1 ## Nextreme™ Value Chiller The Nextreme™ Value Chiller offers OEMs a cost-effective and reliable thermal management solution that keeps sensitive electronics in industrial and analytical equipment at the optimum temperature. Based on the Nextreme Performance Chiller Series design, the Value line offers the same ease of use, low maintenance features and high coefficient of performance (COP) as the performance chiller but at a lower cost to provide a more competitive pricing of an OEM bundled solution. Most importantly, the Value Chiller can be configured to meet unique application requirements. By using environmentally friendly R513A refrigerant, Nextreme Chillers achieve similar performance with half the Global Warming Potential (GWP) compared to traditional hydrofluorocarbon (HFC) refrigerants. Units run on universal input 230V, 50/60Hz, which means that they can operate anywhere in the world.

Semi-Closed Fluid System Sealed fluid system with breathable reservoir cap (similar to an automobile). This prevents evaporative loses, introduction of bacteria, and the need for components to prevent fluid from draining back into the system when installed below the application. Optical Fluid Level Switch Fluid level sensing with no moving parts. RS-232 Communications Complete control integration of chiller into higher level assembly control system. ### Accessory Kits Feature Kit Part Number Description ![](/thermal-wizard/images/accessories/flow-control-kit-thumb.png) Flow Control Valve and Flow Sensing Kit 387004277 This externally installed valve is for reducing the overall flow to the application. Full flow continues through the chiller to maintain high heat transfer rates and temperature stability. The flow meter is for measuring coolant flow rate and is installed externally to the chiller with both a local display (GPM) and connectivity to the chiller LCD display. The flow rate local display is only on NRC products. This kit is for all refrigerant chillers: EFC2400, NRC1200, NRC2400, NRC5000, VRC1200, VRC2400, and VRC4500. ![](/thermal-wizard/images/accessories/water-filter-thumb.png) Water Filter Kit 387004279 Hot swappable, 5-micron water filter for filtering particulates from the coolant circuit. ![](/thermal-wizard/images/accessories/flow-bypass-kit-thumb.png) Flow Bypass Kit 387010608 This externally installed valve is for reducing the overall flow to the application. Full flow continues through the chiller to maintain high heat transfer rates and temperature stability. This kit does not contain a flow meter. ![](/thermal-wizard/images/accessories/pressure-bypass-kit-thumb.png) Pressure Bypass Kit 387010420 This pressure bypass kit prevents high pressure operation and can either operate partially open or open when there is a change in operation (e.g., flow to application stopped). It can be used for flow control but operates with less precision. This pressure bypass maintains full flow through the chiller heat exchanger. ### Cord Options These power cords have been tested and validated on Nextreme devices. Power cord is not supplied with the unit and must be ordered separately.
