BS-608DD 608 L Programmable High and Low Temperat | RFQ Sourcing Details

The BS-608DD is a programmable high and low temperature test chamber designed to expose test samples to high temperature, low temperature, and alternating temperature conditions. Its stated effective volume is 608 L, with internal chamber dimensions of 800 × 950 × 800 mm (W × H × D).

The specified operating range is -40 °C to 150 °C. Published no-load performance data includes a heating rate of at least 3 °C/min from -40 °C to 150 °C and a cooling rate of at least 1 °C/min from 150 °C to -40 °C. These rates are defined as full-process, nonlinear values.

Temperature display accuracy is 0.01 °C, with stated temperature deviation of ±2 °C, fluctuation of no more than ±0.5 °C, and uniformity of no more than 2 °C. The source states that these performance indicators were measured with no sample load at an ambient temperature of 25 ±2 °C.

The chamber uses compressor-based refrigeration, an air-cooled condenser, forced internal circulation with top supply and bottom return, and a Tecumseh hermetic compressor. The inner chamber is made from 1.0 mm SUS 304 stainless steel and has a reinforced bottom with a stated average load capacity of at least 300 kg.

The outer shell uses 1.2 mm cold-rolled steel plate, while the insulation layer is specified as 100 mm rigid polyurethane foam. A 7-inch color touch screen and PLC provide rated-value, program, and slope operating modes.

The controller supports 1 to 120 test programs and up to 1,200 action steps, with a maximum single-step duration of 9,999 hours and 59 minutes. Built-in logging is stated to retain three months of continuous operating data.

USB, RS485, and LAN connections are listed for computer control, storage, printing, and recording.

Physical features include a heated observation window, interior lighting, two adjustable stainless-steel shelf-bracket sets, a 50 mm test port, a three-color status light, drainage troughs, a pressure-balance hole, and swivel casters.

Listed protection functions cover compressor pressure and overload conditions, fan overcurrent and over-temperature, phase loss and sequence errors, leakage, enclosure grounding, and independent chamber over-temperature protection.

Procurement confirmation: buyers should request the final approved configuration and 3D drawing before ordering, because the stated external dimensions are subject to final confirmation. Confirm whether the required test load changes heating, cooling, deviation, fluctuation, or uniformity performance.

Also verify electrical connection requirements for the stated 380 V, 8.5 kW supply;installation clearance and site conditions;included shelves and accessories;controller interface functions;applicable acceptance procedure;delivery schedule;packing dimensions and weight;and the exact scope and duration of warranty and after-sales support.

The source contains differing warranty and after-sales periods, so these terms should be resolved in the purchase contract.
