Recirculating Chiller — Used Bay Voltex MC300-E1PSH4C5 (Bay Voltex)

How Much Does Used Bay Voltex MC300-E1PSH4C5 Cost in 2026?

The used Bay Voltex MC300-E1PSH4C5 recirculating chiller is currently priced at $4,500 in 2026, with condition grade B units typically falling within that range. Units in higher condition grades (A or A-) may command up to $5,500, while those in lower condition (C) might be available for as low as $3,500. Refurbishers like Ferrotec and Axus Technology commonly handle this model, offering warranties from 6 to 18 months depending on the rebuild quality. Compared to a new unit, which can cost between $10,000 and $12,000, you can expect to save 40–60% by purchasing used. However, a failure in this chiller could lead to $2,000–$5,000 in downtime costs per hour in a production environment. It's also important to note that units over 10 years old may require more frequent maintenance, with a 30% higher risk of component failure.

Used Bay Voltex MC300-E1PSH4C5 Specifications and Compatible Tools

The MC300-E1PSH4C5 is a recirculating chiller designed for precision temperature control in semiconductor and industrial applications. It typically features a cooling capacity of 300 W, a temperature range of 5°C to 45°C, and a flow rate of up to 10 L/min. The unit commonly weighs around 120 kg and operates on 230V single-phase power. These chillers are often used in conjunction with deposition and etch tools from manufacturers like Lam Research and Applied Materials, particularly in systems deployed between 2008 and 2015. However, they are not compatible with newer models such as the Lam Centura 5500, which requires a higher flow rate and different control interface. A failure in this chiller due to incompatibility could lead to overheating of the process chamber, resulting in $3,000–$7,000 in tool damage and downtime.

What to Check Before Buying a Used Bay Voltex MC300-E1PSH4C5 in 2026

1. Cooling Capacity Test: Confirm the unit can maintain a stable 300 W output under load. A drop below 250 W may indicate degraded performance.
2. Pump and Flow Rate: Use a flow meter to verify the pump delivers at least 8 L/min. Anything below 6 L/min should be a hard reject.
3. Compressor Health: Check the age of the compressor. Units with compressors over 8 years old may fail within 6–12 months.
4. Control Board and Sensors: Run a full diagnostics test using the onboard system or an external multimeter. Look for error codes related to temperature sensors or control logic.
5. Coolant and Tubing: Inspect for signs of corrosion or mineral buildup in the coolant lines. A unit with more than 2,000 operating hours without a coolant flush may have reduced efficiency.

Purchasing a poorly maintained unit could lead to a breakdown within the first 30 days, costing $1,500–$3,000 in emergency repairs and downtime.

FAQ

Q: How does the MC300-E1PSH4C5 compare to the newer MC500 models?
A: The MC500 offers a 500 W cooling capacity and improved flow rates up to 15 L/min. However, the MC300 is still suitable for older tools and is 40–50% cheaper to purchase and maintain.

Q: Can I use the MC300-E1PSH4C5 with a 2018 Applied Materials Centura tool?
A: No. The Centura 2018 requires a chiller with a minimum of 400 W cooling and a digital control interface. The MC300 lacks both and should not be used without an external adapter, which is not recommended.

Q: How long can I expect the chiller to last with regular maintenance?
A: With annual coolant flushes and bi-annual pump inspections, the chiller can last 8–10 years. Units over 12 years old should be replaced or upgraded.

Q: What are the most common failure points in this model?
A: The compressor and temperature sensors are the most common failure points. A failed compressor can cost $1,000–$1,500 to replace, while sensor issues are often resolved with a $200–$300 part swap.

Q: Should I buy a used chiller if I need it for 24/7 operation?
A: Only if the unit has been fully refurbished within the last 2 years and comes with a 12-month warranty. Otherwise, a 24/7 failure could cost you $5,000–$10,000 in lost production.
