Data Center Power & Heat Testing Solutions
Watlow delivers fully integrated ASME-rated circulation heater and control systems designed for high-performance thermal load demand in liquid load banks. Our engineered systems minimize leak points, ensuring safety, reliability and maximized uptime while providing a high-level of accuracy in simulation. We partner with you to make your solution stronger.
Elements of the Integrated Thermal System
Process Heaters
Watlow’s circulation or flanged immersion heaters for cold starts, minimum loop temperature, ΔT hold, and thermal demand simulation.
SCR Power Control
The Watlow ASPYRE® intelligent SCR for the delivery of precise RMS power, with phase-angle or zero-cross firing and advanced load diagnostics.
Temperature & Process Control
The Watlow EZ-ZONE® RM multi‑loop control for thermal demand simulation in ramp and soak profiles, dew‑point guard, high‑limit logic, data logging, and connectivity to the BMS.
Instrumentation
3‑wire RTDs at heater inlet and outlet and at rack supply and return. Flow and differential‑pressure inputs to the EZ-ZONE® RM around strainers and heat exchangers. One room RH and dry‑bulb input for dew‑point calculation.
Human Machine Interface (HMI)
The Silver Series EM is a rugged, touchscreen operator interface terminal (OIT). Available in three sizes (4.3, 7 and 10 inch diagonal display sizes), the OIT’s feature serial and Ethernet communications with multiple controllers, e-mail messaging, universal serial bus (USB host), data logging, flexible password security and multiple languages.
Why Choose a Watlow Integrated Thermal System?
- One supplier for heaters, SCRs, controllers, instrumentation, and panels
- Fewer interfaces and faster FAT and SAT
- Repeatable simulations with logged evidence and standard BMS integration
- Global support, service level agreements, and expert engineering capability
Make Liquid Load Banks Safer and Smarter for Your Data Center
Watlow provides a fully integrated thermal system that converts load-bank heat into a controlled, repeatable simulation. In a typical load bank, circulation heaters produce heat only when the electrical system is under load. Instead, use a separate circulation heater to address three key gaps:
Cold Starts and Freeze Protection
Hold a minimum secondary loop temperature in winter and during low-load maintenance windows.
Hydraulic Proving
Prove pumps, valves, and outdoor heat rejection before you energize PDUs and UPS. Separate cooling issues from power issues on day one.
Dew Point Margin
Keep supply temperature a few degrees above room dew point while you tune CDU and outdoor unit controls.
