Medical Refrigerators & Freezers

Our medical refrigerators and freezers accommodate diverse temperature needs to securely store samples, research materials, culture media, pharmaceuticals, and blood products. They also offer reliable long-term preservation for biological resources like frozen cells.

PHCbi’s MDF Ultra-Low-Temperature Freezers and Cryogenic Freezers excel with advanced refrigeration technologies.
These units incorporate control, alarm, monitoring, and accessibility features to ensure consistent sample preservation.

Discover all our preservation solutions to find the ideal fit for your requirements.

• What do the "Error" or "Function" codes on the product display mean?

  The meaning of "Error" and "Function" codes varies by model. An "Error" code indicates an abnormal condition, while a "Function" code signals the need for part replacements, such as the fan motor or battery, after its lifespan.
  
  For models with an LCD display, not only codes like "Warning," "Alarm," or "Status" are shown, but also clear messages. These messages allow users to quickly understand the situation without referring to the manual.
  
  For more details on specific codes, consult the User's Manual or contact your sales representative or distributor for support.

Ultra Low Temperature and Biomedical Freezers

• What type and amount of CFC gas/refrigerant is used in the equipment?

  The type and amount of chlorofluorocarbon (CFC) gas are displayed on the nameplate along with the product name and serial number. While the nameplate location varies by model, it is typically found on the side of the cabinet.

• What should I check if nothing works when the power is turned on?

  Please review the following:
  - Is the outlet plug properly connected, and is the power capacity sufficient?
  - Has there been a power failure, a tripped breaker, or a blown fuse?

• How do I stop the alarm on an Ultra Low Temperature Freezer?

  Press the "Buzzer" key on the control panel or LCD touchscreen to silence the alarm. If the ring-back function is enabled and the alarm condition continues, the buzzer will sound again after a set time. Please note that alarm tests cannot be silenced this way. For more details, consult the User’s Manual.

• Is the product frost-free?

  The products are not fully frost-free, as frost can occur based on usage conditions such as humidity, ventilation, and door openings. However, anti-frost features minimize this issue:
  
  - ULT Freezer (-152°C/-80°C): Manual defrost required. Frost removal needs the freezer to be turned off after transferring samples to another freezer.
  - Medical Freezer (-30°C/-40°C), including Pharmaceutical Refrigerators with Freezer: Depending on the model, either manual or automatic defrost is available. For example, the MDF-U443 offers automatic defrost.
  
  - MDF-U443 Automatic defrost: Occurs every 12 hours with minimal temperature rise, allowing items to remain inside. More details are available in the manual.
  - Hot Line for Sealing: To prevent moisture and frost buildup, hot gas circulates through key areas.
  - Fivefold Gasket VIP ECO, TwinGuard series): A specialized gasket structure reduces frost formation and minimizes defrosting frequency.
  
  
  
  Tips to Minimize Ice Buildup:
  - Position the freezer away from vents and drafts.
  - Limit door openings and ensure doors are securely closed.

• What is the difference between Temperature Setting Range and Temperature Control Range?

  - Temperature Setting Range: The temperatures you can set via the control panel.
  - Temperature Control Range: The actual temperature range the freezer can maintain under specific conditions, such as 30°C ambient temperature, air temp measured at the center, and no load (as described in the manual or brochure).
  
  Even if you set the freezer to -90°C, operating it at the extreme end of the range can strain the unit. The Temperature Control Range reflects the guaranteed performance.

Pharmaceutical Refrigerators

• What should I check if nothing works when the power is turned on?

  When the power is on, but the unit is not functioning, please check the following:
  - Is the outlet plug properly connected, and is there enough power supply capacity?
  - Is there a power outage, a tripped breaker, or a blown fuse?

• Why is there condensation or moisture on the fridge door?

  1. How condensation forms
  - Ambient temperature and humidity: Condensation on the glass or door frame of a lab/vaccine refrigerator can vary based on environmental conditions. It happens when the surface temperature differs from the room's temperature and humidity, especially in warm, humid environments.
  
  2. Possible causes of condensation
  - Case 1: No condensation during the day, but visible in the morning.
  Insight: The air conditioner may run during the day, dehumidifying the air, but once off, humidity rises overnight, causing condensation.
  - Case 2: Condensation recently started forming.
  Insight: A higher air conditioner setting for energy savings may cause this.
  - Case 3: Condensation occurs while using the fridge.
  Insight: Frequent door openings let cold air escape, cooling the glass and leading to condensation.
  - Case 4: Condensation varies between units in the same room.
  Insight: Air conditioner airflow may affect units differently depending on their position.
  - Case 5: Condensation appears more on the lower part of the door.
  Insight: Cold air tends to settle at the bottom, causing condensation to form there first.
  
  Tips to minimize condensation on lab/vaccine refrigerators It's normal to see some condensation on the glass door in high humidity or temperature environments. As long as the unit's storage conditions are maintained, this doesn't affect stored items. For best results, install the unit in a dry, well-ventilated area away from direct sunlight. If condensation persists, improve the room’s air conditioning or reduce humidity as needed.
