AIRSYS VENUS-ECS05 process-temperature chiller

A compressor-based semiconductor-tool temperature-control model whose linked table gives 10 to 60 °C, rather than the landing page's broad −80 to 80 °C wording.

01 / UNDERSTAND THE EQUIPMENT

Resolve the ECS05 temperature range and fluid duty against the actual tool

VENUS-ECS05 is labelled the compressor-type constant-temperature liquid-cooling unit in AIRSYS's linked VENUS brochure. The model table specifies 10 to 60 °C, ±0.1 °C control accuracy and 10 kW cooling at a stated +20 °C point. It identifies FC-3283 as the heat-transfer fluid and R-404A as the refrigerant. Those are different circuits and substances.

The live VENUS landing page puts a broad −80 to +80 °C range and 1–20 kW capacity under ECS05. That does not agree with the linked model table. This brief uses the table's actual conditions as the documented example and makes the conflict visible. A buyer needs a current supplier-confirmed ECS05 selection, not a merged range assembled from the whole VENUS family.

Selection and application review

Obtain one controlled revision before specifying low temperature

The ECS05 landing-page range reaches −80 °C; the model table starts at +10 °C. The family brochure separately contains a low-temperature CS10LT model. That difference matters to procurement: the page does not establish that the tabulated ECS05 can operate at the lower temperatures. Ask AIRSYS to identify the exact variant, corrected range and current revision, and to provide the selected capacity at every required setpoint.

Do not use a family marketing range to meet a tool's low-temperature requirement. Specify the actual required steady-state temperature, transition profile and ambient envelope. A quoted model substitution should include its own fluid, electrical and connection documents.

Define what ±0.1 °C is measuring

The ECS05 table prints ±0.1 °C control accuracy without stating the measurement location, load profile or time interval. The brochure shows high-reliability refrigeration parts and transient-power protection, but supplies no witnessed stability trace for this order. Agree where the temperature is measured and what excursion, recovery and repeatability are allowed.

Use the semiconductor-tool vendor's interface to define the load cycle and permitted inlet conditions. Request a test covering the proposed piping/volume and the relevant heating/cooling changes. The published accuracy should not be presented as wafer, chamber or process-result accuracy.

Keep the transfer-fluid loop separate from refrigeration

The ECS05 model table identifies FC-3283 in the circulating loop and R-404A in the compressor circuit. Approve the actual transfer fluid, materials, hoses, seals, connectors and fluid preparation against the tool requirements. Ask which fluid is delivered, who fills the tool loop and what maintenance or handling documents accompany it.

The 10 kW cooling point is at +20 °C; the 25 L/min / 0.5 MPa row also references +20 °C. Obtain the selected pump curve and pressure limits, including the allowed tool pressure and actual hose/manifold losses. The table does not prove that every listed maximum can be delivered together.

Account for heating, rejected heat and power

The table lists two 1.0 kW heaters and an 8.2 kW input entry. Cooling capacity, heater rating and unit input are different quantities. Obtain the electrical load schedule, mode-dependent input, starting/control behaviour and the applicable installation/protection instructions rather than treating the cooling capacity as electrical consumption.

The tabulated envelope is 400 mm wide, 900 mm deep and 1,500 mm high. No service-clearance or heat-rejection connection diagram is included in the reviewed model spread. Ask for the current general arrangement, access route, heat-rejection boundary and connection schedule before committing to a tool bay.

Close controls and factory acceptance with the tool integrator

The table lists Analog/Digital/Serial interfaces but not signal ranges, protocol, point map, fail state or interoperability with a particular process tool. Define enable, ready, fault, flow, temperature and interlock responsibilities using the current OEM requirements. Obtain the actual communications and wiring documents and include their operation in the factory test.

CE, S-Mark and Semi-S2 appear in the table as design-standard entries, not reviewed current issuer certificates. The brochure describes cooperation with Korea's FST and Chinese local manufacture, but it does not identify the manufacturing serial record for a purchase. Request the actual producing entity, model revision, conformity documents and signed thermal/hydraulic acceptance result. Pricing, availability and process qualification remain unconfirmed.
