BINDER KBF-S ECO 720 Constant-Climate Chamber, Peltier technology, 700 litres, 9020-0418

The BINDER KBF-S ECO 720: Climate testing taken to a new level of efficiency

The BINDER KBF-S ECO 720 (item no. 9020-0418) sets new standards in the field of constant-climate chambers. If you need to carry out long-term stability tests in accordance with ICH guidelines (Q1A) and place a high value on sustainability, low running costs and absolute reliability, this unit is the first choice. With an enormous internal volume of 700 litres, it offers space for countless samples, yet thanks to its innovative thermoelectric cooling, it consumes only a fraction of the energy used by conventional compressor-based units. It is the quietest, most efficient and most environmentally friendly climate chamber in its class – “Made in Germany” by BINDER.

Peltier technology with patented heat dissipation

At the heart of the BINDER KBF-S ECO 720 lies advanced Peltier technology. Unlike traditional climate chambers, this unit requires neither an energy-hungry compressor nor a refrigerant. This brings you key benefits:

1. Energy efficiency: The KBF-S ECO 720 is one of the most energy-efficient units on the market. Particularly during long-term tests lasting months or years (e.g. at 25 °C / 60 % RH or 40 °C / 75 % RH), the lower power consumption makes a massive difference to operating costs.
2. Carbon neutrality: As no fluorinated gases (F-gases) are used, the CO₂ footprint of refrigerants is completely eliminated. You avoid the need for time-consuming leak tests and make an active contribution to environmental protection.
3. Quiet operation: With no compressor humming or vibrating, silence reigns. The cabinet is whisper-quiet and is perfectly suited to laboratories where people need to concentrate on their work.

APT.line™: Uniformity in every corner

A large capacity is of no use if conditions are not the same throughout. With its tried-and-tested APT.line™ pre-heating chamber technology, BINDER guarantees horizontal air distribution from both sides. Whether you store your samples on the lowest or highest shelf, at the front or the back – the temperature and humidity are extremely uniform throughout the entire 700-litre interior. This ensures that all samples are exposed to identical stress conditions, which is essential for the validation of your studies.

Precise humidity management

Humidification is provided by a responsive steam humidifier connected to the water supply (or a canister). Humidity is measured by a capacitive humidity sensor that is drift-free and low-maintenance. The control range extends from 10% RH to 80% RH at temperatures from 0 °C to +70 °C. Even after the door is opened, the system readjusts in a flash to restore the defined parameters.

Well-thought-out design for everyday laboratory use

The BINDER KBF-S ECO 720 impresses with features that make work easier:

• Inner doors made of safety glass: You do not need to disrupt the climate to check the samples. The tightly sealing glass doors allow you to see inside whilst conditions remain stable.
• No condensation: Thanks to the intelligent control system and horizontal airflow, condensation on the samples or the ceiling is effectively prevented.
• Space-saving design: Despite the large interior, the footprint is optimised (“slim design”), meaning the cabinet fits even in narrow corridors.

Safety and documentation

For GMP/GLP-compliant laboratories, the KBF-S ECO 720 offers comprehensive safety features:

• Auto-Fail-Safe: An independent Class 3.1 device (DIN 12880) protects against over- and under-temperature conditions with visual and audible alarms.
• Data logging: Via the Ethernet interface and the (optionally available) APT-COM™ software, all process data can be recorded seamlessly and archived in a tamper-proof manner.

Areas of application

• Pharmaceuticals: Stability testing of medicines (ICH Q1A).
• Cosmetics: Shelf-life testing of creams and lotions.
• Packaging: Testing the barrier properties of films.
• Food: Shelf-life testing (“Best before” determination).

With the BINDER KBF-S ECO 720, you are choosing the future of climate control technology: green, economical and uncompromisingly precise.
