-70℃ Explosion-Proof Water-Cooled Chiller for Medical Industry-BS-45FD

The -70℃ explosion-proof water-cooled chiller adopts a cascade two-stage compression water-cooled refrigeration system with full explosion-proof construction. It can stably supply heat transfer medium at -70℃ with temperature control accuracy up to ±0.1℃. All electrical components comply with national explosion-proof standard Ex d ⅡB T4 (Ex d ⅡC T4 optional). Featuring high-efficiency water cooling and 304/316L sanitary stainless steel pipelines, the unit meets GMP standards for pharmaceutical clean workshops. It is specially designed for pharmaceutical workshops, biological labs and medical lyophilization areas with flammable volatile organic solvents and high-oxygen explosion hazardous zones.

Water cooled  packaged chiller Working Principle

Medical manufacturing widely adopts flammable volatile solvents such as ethanol, acetone, dichloromethane and DMSO. Lyophilization, API synthesis and sample pretreatment areas are classified as Zone 1 & Zone 2 explosive gas hazardous locations:
 
Complete flameproof electrical system: Explosion-proof compressors, explosion-proof motors, flameproof control cabinets, explosion-proof sensors and sealed cable glands eliminate electric sparks that may ignite solvent vapor.Anti-static safety
 
structure: All pipelines, frames and circulating pumps are equipotentially bonded and grounded to prevent static accumulation. Spark-free impellers avoid sparks from metal collision. The maximum surface temperature of the unit is lower than the ignition point of common medical organic solvents.
 
Multi-channel safety interlock protection: Automatic shutdown and audible-visual alarm triggered by over-temperature, high/low refrigerant pressure, insufficient flow, phase loss, overload and medium leakage, fully complying with medical safety supervision standards.

 

Safety Protection Function

  • Stable cooling capacity: Dissipate heat via external cooling towers, free from ambient high temperature impact. Constant refrigeration output during 24-hour non-stop production, ideal for three-shift pharmaceutical manufacturing.
  • Cleanroom compatible: No hot air exhaust to avoid disrupting cleanroom pressure difference, temperature and humidity balance. Low noise operation without interference to precision medical testing equipment.
  • Easy cleaning & sterilization: Mirror-polished stainless steel pipelines with no sanitary dead corners, supporting CIP online cleaning and resisting corrosion, suitable for vaccine and biologic clean production zones.

 

  • Energy-saving performance: Compared with air-cooled explosion-proof low-temperature chillers of the same specification, cooling efficiency increases by over 25% under high-temperature working conditions, cutting long-term operation costs.

FAQ

Q1:What are the requirements for the operating environment of the water chiller?

A1: Generally, the ambient temperature is required to be between 5℃ and 40℃, and the relative humidity should not exceed 85%. At the same time, the water chiller should be placed in a well-ventilated area free from direct sunlight, and away from heat sources and dust. This ensures the normal operation of the water chiller and optimal heat dissipation performance.

 

Q2: What are the causes of poor cooling efficiency in the water chiller?

A2: Possible causes include the following:

 
  • Insufficient cooling water flow: Check if the cooling water pump is working properly and if there is any blockage in the pipes.
  • Excessively high cooling water temperature: Inspect whether the cooling tower is operating normally and ensure unobstructed circulation of the cooling water.
  • Contamination accumulation in the condenser: Regularly clean the condenser to maintain its heat dissipation performance.
  • Refrigerant leakage: Examine the refrigeration system to locate and repair the leakage points.

 

Q3: What causes excessive noise from the water chiller?

A3: Common causes are as follows:

  • Vibration of the cooling water pump: Check if the pump is installed securely and if its bearings are worn.
  • Motor failure: Inspect the insulation performance of the motor and check for bearing wear.
  • Malfunction of the cooling tower fan: Verify if the fan blades are balanced and check for bearing wear.
  • Refrigerant leakage: This can also lead to excessive noise. Inspect the refrigeration system to find and fix the leakage points.
