Import Deep Freezer — Buy in Bulk from Supplier in India

This deep freezer operates within a temperature range of -35°C to -40°C using a cascaded or single-stage refrigeration system with R-508B (Suva-95) and R-404A refrigerants, exclusively R-404A in some models. It features braze plate heat exchangers, high-density CFC-free PUF insulation measuring 100 mm, and an air-cooled condenser driven by a continuous-rated motor fan. The interior uses high-purity copper coils for efficient heat transfer, with stainless steel shelves and walls made of SS-304, 22 SWG, while the outer cabinet is constructed from CRCA with a durable polyester powder coat.

The unit includes sub-doors for internal compartments made of either SS-304 or poly acrylic sheet, cam-action locks, and flat latches to ensure secure sealing. Microprocessor control with password-protected digital temperature display and NTC temperature sensors provide precise monitoring. Audio-visual alarms trigger for temperature deviations and power failures, supported by low battery and hot condenser indicators. Safety interlocks prevent simultaneous operation of both refrigeration stages, and high-pressure switches protect against system overloads.

This freezer is designed for laboratory, medical, and biotech storage where consistent ultra-low temperatures are critical. Buyers include research institutes, blood banks, and pharmaceutical suppliers requiring reliable cold chain integrity. Packaging is standard industrial crate with heavy-duty castors, two equipped with brakes. Trade terms are FOB Chennai, lead time is 15 to 25 days after order confirmation, and payment is typically via T/T or LC. Battery backup and automatic voltage stabilizers with high/low voltage cut-off are included as standard.

The supplier is classified as imported and holds harbor-tier trust status, indicating verified business registration and documented export history. There is no public data on years in operation, employee count, or revenue. The listing confirms manufacturing capability and direct export experience but does not mention certifications, client names, or third-party audits.

The supplier responds to inquiries with zero recorded response rate and no average response time, suggesting limited or delayed communication channels. Despite this, the product description reflects technical familiarity with lab-grade freezer design, including specific refrigerant choices and safety interlocks. Buyers should treat this as a manufacturer with production capacity but unverified customer service responsiveness. Direct technical verification is recommended before order placement.
