Patented VIP Vacuum Insulation Panels

PHC was the first company to introduce vacuum insulation panels to ultra-low temperature freezers. The PHCbi range of freezers with VIP® insulation typically provide 30% more storage capacity for a given floor area saving valuable laboratory space.
The PHCbi patented VIP vacuum insulation panel thin-wall composite is a high-efficiency design that yields more interior storage volume in a conventional freezer footprint.
