Inner Doors:

• To minimize temperature changes while the main door is opened, the upright freezers have inner doors made of anti shock panels in polystyrene on a polyurethane core.
• The chest freezers have a polyurethane lower lid with an aluminum finish.

Internal Chamber:

• Made with AISI 304 8/10 stainless steel with round corners rounded for easy cleaning.
• The copper tube wraps around the chamber and is fixed using a proprietary process enabling excellent temperature uniformity.

• CFC-free polyurethane (high pressure “sandwich" injection technique).

• Average thickness 140 mm.

Cooling System:

• Completely sealed and based on a proprietary cascade cycle (single stage for -400C models) using two hermetic compressors with environment-friendly CFC.
• HCFC-free refrigerant gas, with ODP=O (ozone distribution power).
• R404a in the first stage and a gas mixture in the second stage.
• Air condensation is done without any water connection. The sealed hermetic system enables a very low noise level (max 53 db) and a long life without special maintenance.

Port Hole:

• 23 mm access port hole with rubber cap to enable electrical or additional probe connections.

BIOGUARD ® (Models PLUS):

• This system enables the door opening(by authorized personnel only) through a tag.
  CRYOLOG, the software (WINDOWS) for the freezer management (runs up to 10 freezers or refrigerators equipped with BIOGUARD®), is available as an option.
