How Do Impulse Sealers Impact Space Conditioning
Employers are required by rules and regulations to maintain reasonable temperatures within the working environment to ensure their employees’ health and safety.
While reasonable temperatures obviously depend on the nature of any given environment/ work to be carried out (a bakery, for instance, would be hard pushed to maintain low temperatures, while cold storage units would be rendered useless if temperatures were raised above a certain level), data provided by the OSHA (Office of Safety and Health Administration) states that the maximum temperature of standard working environments should not exceed 78 degrees F (25 degrees C).
For most companies, this means air conditioning is used to keep temperatures at acceptable levels.
Unfortunately, some machinery gets hot, while other equipment requires heat to operate.
If such equipment remains at high temperatures on a continual basis, such as a constant heat sealer, for example, the emitted heat constantly raises the surrounding temperature, making it necessary for AC units to work harder and subsequently increasing energy costs substantially.
This particular problem is easily avoided by using ONPUL impulse heat sealers. The main difference between impulse and constant heat sealers consists of the fact that impulse sealers do not require pre-heating and will only heat up when actually in use. This has a range of beneficial effects. To begin with, impulse heat sealers are immediately ready for action – which is achieved by delivering an impulse of high current to the unit’s heater ribbon. This means there is no time wasted by waiting for the unit to heat up, reducing both packaging times and labor costs.
Secondly, energy is only consumed when the unit is in use, meaning running costs are reduced substantially in comparison to those of constant heat sealers.
Thirdly, and in the present context most importantly, there are no continually hot surfaces on impulse heat sealers, which means no unnecessary heat is released into the environment. On delivery of current to the heater, the temperature is raised to the desired level, which can be set to precise specifications and is constantly monitored and kept at the required level by low-profile sensors located on the heater blades and a micro-computer control unit.
Once the sealing process is completed, the current to the unit’s heater ribbon stops and the unit cools down, during which the seal remains under pressure. As a result, surrounding temperatures remain comparatively low and the cost of running AC systems is subsequently kept at a minimum. The lack of continually hot surfaces also reduces the risk of accidental injury to employees, a risk that is continually a factor when using constant heat sealers.
Another benefit of this process is the consistently high quality of seals produced.
In addition to the above mentioned issues, constant heat sealers have two main disadvantages – the risk of over-heating and fluctuating temperatures – which are caused by the continual ‘battle’ between the heater trying to keep the necessary temperature to provide seals and the AC unit kicking in and supplying cool air in order to maintain acceptable environmental temperatures – both of which invariably result in deterioration of seal quality.
Because the temperature generated by impulse heat sealers is constantly monitored and adjusted as and when required to precise settings, seals will remain both strong and clean even during high volume production/ packaging runs. The fact that seals are kept under pressure during the cooling process further ensures that packaging remains even, which is an issue often causing problems when constant heat units – which are prone to loss of pressure due to both cooling and fusion taking place during the shrinking process – are used.
To put it into a few simple words, impulse heat sealers provide clean, even and continually strong seals without causing your energy, labor and space conditioning costs to spiral out of control.
