Shock Freezer TPSU Series -50°C to -80°C
GENERAL STRUCTURE – External cabinet made of zinc-plated and/or enameled steel sheets, o r, upon request, SI 304 stainless steel satin finish. – Insulation in non-CFC, non-HCFC foamed polyurethane – Internal casing in AISI 304 (or AISI 316 upon r equest) stainless steel, with polished exter nal BA finish for maximum resistance and cleanliness; LIFETIME WARRANTY ON STEEL PARTS – Triple-step seal in silicone rubber for greatest prevention against air loss and ice formation; gaskets with almost unlimited durability. – Gasket heating by means of the r efrigerant pipes on the overheated-steam side; the safest solution against ice formation, more reliable and with greater energy saving (in fact, it does not use additional sources of heat like electric resistances, etc.) – Complete reheating compensation valve to equalize inter nal and external pressure after opening and closing the door: greatly facilitates being able to open the door after it has been opened not long ago. – Four internal stainless steel shelves, standard in vertical models – Insulated counter doors (in vertical models) with 20-mm. poly urethane foam, to minimize cold loss when the external door is opened; – Insulation panels (in horizontal models) with 20-mm. polyur ethane foam, to minimize cold loss when the external door is opened; – Highly ergonomic closing handle (in vertical models) to facilitate closi ng: just one hand and minimum force applied – Locking handle with self-raising hinges (in horizontal models ) for maximum ease when closing and maximum operator safety. – Lock and key for all locks – Loading System: Our innovative solution gives you the possibility to quickly load the freezer with the help of a trolley. This way the whole racket system is inserted into the freezer, giving you the chance to freeze the plasma, in the fastest time, in 2.15 minutes. – Pivoting wheels for maximum freezer maneuverability inside the laboratory – Insulation with CFC- and HCFC-free polyurethane resin foamed on site, with an average thickness above 140 mm – Lock with transponder/badge available (optional); the PK (Per sonal Key) device comes complete with badge reader, management electronics, stabilized power supply at 12 Vdc 3 A and microelectronic security pistons. It is integrated with the closing system.
