Recycling Batteries Responsibly

  • The European Directive on Batteries and Accumulators aims to minimise the impact of batteries on the environment and encourage the recovery of the materials they contain. In the UK, regulations on the recycling of batteries and accumulators (rechargeable batteries) were Introduced in 2009. The Waste Batteries Regulations aim to significantly increase UK collection and recycling of used portable batteries from 3% in 2007 to 25% by 2012, rising to at least 45% in 2016.

  • The battery symbol on a product or on its packaging indicates that the product must not be disposed of with general household waste. Instead, it is the consumer’s responsibility to dispose of their waste batteries at a designated collection point so that they can be recycled. The separate collection and recycling of batteries at the time of dispo sal will help to conserve natural resources and ensure that they are recycled in a manner that protects human health and the environment. A comprehensive list of battery recycling centres can be obtained from:

  • All Samsung products that are subject to the Batteries Directive are compliant with the UK battery and accumulator Requirements. In accordance with national law, SAMSUNG Electronics (UK) Ltd is a member of an approved batteries producer compliance scheme. This scheme collects, treats and disposes of batteries on Samsung’s behalf.

  • Samsung’s versatile air conditioning system allows up to five indoor units and uses minimal installation space
  • It’s a solution that's both practical and effective

BLDC (Twin Rotary) Compressor

BLDC (Twin Rotary) Compressor
A key contributor to the FJM’s efficiency is its BLDC (Twin Rotary) Compressor, which is featured on all outdoor models. Its twin eccentric cams and two balance weights result in extremely low levels of vibration, contributing to a much quieter all-round performance. Attention to the quality of moving parts such as robust bearings, as well as premium matching rollers and vanes produce a high degree of stability and durability.

Reduced Vibration and Noise

Reduced Vibration and Noise
All new FMJ outdoor models incorporate the TBR Sine-Wave Compressor in addition to the twin BLDC compressor. This serves to reduce torque variation by 70 per cent and vibration by 80 per cent compared to a regular single compressor. As a result, stress on the motor is kept to a minimum, and the lifespan of the air conditioning unit is extended. A further benefit is a significant reduction in noise, leading to a more comfortable and productive working environment.
Wide Operation Range Of Outdoor Temperature

Wide Operation Range Of Outdoor Temperature

No matter how extreme the temperature, our FJM air conditioning unit will handle the situation. It is able to cool in heats of up to 50°C and provide warmth in -20°C, eliminating the need for any additional units to cope in times of adverse weather. Its smart inverter system delivers the required temperature quickly right from start up, and continuously performs fine-tune adjustments to ensure a constant and comfortable environment.
