ChillZilla ® LN2 Liquid Supply System

Bulk LN2 Supply Management System

ChillZilla SchematicThe ChillZilla bulk LN2 Liquid Supply System is engineered to provide consistent liquid nitrogen for optimum equipment performance. Ideally suited for Individually Quick Frozen (IQF), LN2 immersion freezers and cryobiological storage freezers, the ChillZilla LN2 system features a Dynamic Pressure Builder™ for precise saturated liquid supply to the freezer regardless of the LN2 liquid level. The ChillZilla system incorporates an insulation baffle to inhibit the mixing of fresh liquid from a trailer load delivery with the liquid supply to the freezer for better liquid supply stability during the refill.

With the aid of a patented high performance two-stage ambient pressure building coil, the heat management of this circuit is optimized for fast pressure recovery and reduced heat transfer to the contents. Coupling these unique features with the temperature monitoring of the liquid supply, a Programmable Logic Controller (PLC), VJ feed valve with an extended VJ pod and extended legs, the ChillZilla LN2 system automatically provides the optimum liquid nitrogen supply to any liquid application.

Ideally suited for other LN2 applications with the same demand, like cryogenic rubber and tire deflashing.
