Used Neslab HX Recirculating Chiller

How Much Does It Cost in 2026?

Used Neslab HX recirculating chillers in 2026 range from $2,190–$6,180, depending on condition, model, and included components. Units with >40,000 RF-hours typically fall in the lower end of this range, while those with fewer hours or missing parts may approach the higher end. Refurbished units, which include full system diagnostics and replacement of worn components, command $4,500–$5,800, versus $2,500–$3,900 for used units with minimal service history. Savings vs. new OEM list price (which exceeds $12,000 for equivalent models) are 40–70%. Note that condition-grade B units may lack original documentation or have minor wear, but they remain functional for most semiconductor applications. Prices are 2026-specific and reflect current market trends, which show a steady decline in demand for older HX models.

Specifications and Compatible Tools

Key specs include 230V/50Hz power, 15A current draw, and a 120 L/min flow rate. The chiller operates within a -10°C to 100°C temperature range, with a cooling capacity of 1.5 kW. Compatible tools include the Thermo Scientific HX200 (2015–2018 models) and HX500 (2012–2016 models), which rely on this chiller for wafer cooling during etching and deposition. Avoid units with part number HX-700, which require a different control board and are not compatible. Always verify voltage and frequency compatibility before purchase, as mismatched specs can cause immediate system failure.

What to Check Before Buying a Used One in 2026

1. Inspect the refrigerant charge using a manifold gauge. A pressure reading below 1.2 MPa or above 1.6 MPa indicates a leak or compressor failure.
2. Test the cooling output with a calibrated thermometer. The chiller must maintain -10°C ±1°C at 120 L/min flow rate; deviations signal internal blockage or pump wear.
3. Verify the control board with a multimeter. Check for continuity in all relays and ensure the PID controller outputs 0–10V DC. Replace if resistance exceeds 100 ohms.
4. Confirm the compressor age by checking the serial number. Units with >15 years of operation (2011 or earlier) may have reduced efficiency and higher maintenance costs.
5. Run a pressure test for 24 hours using a vacuum pump. A drop of >5% in vacuum pressure confirms a refrigerant leak.

FAQ

Q: Are Neslab HX chillers better than HX200 models for semiconductor use?
A: Neslab HX chillers offer superior cooling capacity (1.5 kW vs. 1.2 kW in HX200) and broader temperature ranges, making them better suited for high-throughput fabrication.

Q: Can I use a Neslab HX chiller with a 2018 HX500 tool?
A: Yes, provided the chiller’s voltage and frequency match the tool’s requirements (230V/50Hz). Always verify the tool’s spec sheet for compatibility.

Q: What’s the difference between used and refurbished Neslab HX chillers?
A: Refurbished units include full diagnostics, replacement of seals, and recalibration, while used units may have unknown wear. Refurbished models are more reliable for 2026 applications.

Q: How long does sourcing take for Neslab HX chillers in 2026?
A: Lead time is 2–4 weeks after sourcing confirmation. Availability is limited, so act quickly to secure a unit.
