Climcel- Thermal Batteries
CLIMSEL – HIGH QUALITY PCM
PCM technology provides a safe, flexible and efficient solution for energy storage, temperature regulation and temperature stabilisation. ClimSel is a leading solution in this area which, together with our extensive expertise in project-adapted PCM packages, provides strong customer benefits. Each ClimSel product is an autonomous solution for energy storage and temperature regulation, suitable for all environments and applications. Through our extensive know-how and resources for laboratory testing, we can develop ClimSel solutions based completely on each project’s unique requirements and needs.
We work in four different product areas.
PCM – PHASE CHANGE MATERIALS
Brio Climator’s product solutions are based on various types of PCM – Phase Change Materials. These are materials that, through their special phase change properties, have the ability to store energy for an extended period of time.
For this reason, PCM technology can be used for safe temperature stabilisation and thermal energy storage in many different applications. Commercially, PCM is available in a variety of types, with different base materials for the phase change. What distinguishes Brio Climator’s PCM, ClimSel, from most other materials is that the phase change – the transition from the frozen to liquid phase or vice versa – takes considerably longer and is stable over time. These are the key characteristics that make ClimSel an optimal choice for efficient temperature stabilization.
CLIMSEL – THE LEADING PCM SOLUTION
ClimSel is a salt-based, high quality PCM with excellent phase change properties. Through innovation and product development. Better energy storage capacity, better user economy and a much more environmentally-friendly makes it the most innovative product today.
Extensive knowledge of ClimSel and PCM, combined with our experience in various types of packaging and logistics solutions, makes Brio Climator a safe and natural choice for reliable temperature stabilisation and thermal energy storage.
ClimSel is a water-soluble, non-flammable, inorganic product with high enthalpy (amount of energy for the phase change). It is stable over time with virtually infinite life and an infinite number of charging cycles. These properties make ClimSel both environmentally friendly and a long-term sustainable alternative. Moreover, ClimSel is characterised by significant inertia in charging and discharging, which, in turn, provides long-duration energy storage and, thus, unbeatable temperature regulation.
TYPICAL AREAS OF APPLICATION
Temperature protection of sensitive, valuable freight including pharmaceuticals, foods, and human/animal organs. With ClimSel PCM, a microclimate is created to keep your cargo within the correct temperature range at all times, whatever the ambient temperature.
Energy storage in buildings – embedded in the structure or held in storage tanks. Thanks to its capacity to store cooling or heating energy, ClimSel PCM is a smart, highly energy-efficient part of today’s indoor climate solutions
Temperature-regulating, protective clothing with integrated ClimSel PCM elements can provide professionals, athletes and working animals and pets with an autonomous system for protection against heat or cold.
Cooling and temperature stabilisation of electronic and mechanical equipment. ClimSel PCM provides secure protection during temporary temperature peaks, as well as cyclical fluctuations in ambient temperature.
HOW DOES CLIMSEL WORK?
We can compare ClimSel with a battery. The difference is that a battery stores electricity while ClimSel stores energy. This energy storage comes courtesy of the phase change properties of ClimSel and PCM. Nature’s most common PCM – phase change material – is water which, as we know, goes from solid to liquid, i.e., makes a phase change at around 0°C. The characteristic aspect of this phase change is that it is highly energy-intensive. The energy provided is primarily used to change the material’s phase (from solid to liquid or vice versa), and not to change its temperature during the phase change, thereby providing a virtually constant temperature.
The illustration above shows how the material is affected during the phase change from the solid to liquid state.
When the material is in a solid state, there is an increase in temperature as energy is provided. In contrast, when the material enters the phase change zone, the energy provided is used for the phase change, i.e., the gradual transition from solid to liquid form. During this phase,there is no increase in the temperature of the material. Once the phase change has been completed and the material is completely liquid, the energy provided results in the temperature of the material starting to rise again.
By making use of the properties of the phase change, ClimSel can actually move energy in time and create a temperature range at the required temperature level. The phase change takes place at different energy levels for different ClimSel products – from approximately – 21°C/-5.8°F to + 70°C / 158°F. The choice of specific ClimSel product can, therefore, be based on the temperature levels that apply for each application.
FREEZING AND MELTING PROCESS
Each ClimSel product has a unique phase change process and specific thermodynamic properties that make them suitable for customer applications in different temperature ranges. The products’ unique phase change characteristics are illustrated by the graphs on each product sheet. Here we explain the phase change process, using ClimSel C7 as an example.
The red line indicates the so-called melting curve where the ambient heat load is greater than the required temperature. The blue line indicates the so-called freezing curve where the ambient heat load is lower than the required temperature.
ClimSel C7 is a standard material in transport. For example, ClimSel C7 can be used
to create a microclimate in the temperature range 2-8°C/35-46°F.
1. For shipments where the ambient temperature in the cargo space is higher than the required temperature, ClimSel C7 is charged at a temperature below 3°C/37°F. The cargo is then placed in a transport box with ClimSel and the transport begins.
2. ClimSel C7 is now in a frozen (solid) state and the unique ClimSel’s unique characteristics become evident. That is, the ambient temperature load (the heat) does not result in the PCM significantly increasing in temperature. Instead, the energy is consumed by the phase change and the melting process begins. Thus, the climate in the transport box is maintained within the pre-determined range and there is no significant increase in temperature.
3. Only when the PCM has completely melted – and the phase change completed – does the temperature start to rise.
1. For shipments where the cargo must be protected from the cold, the reverse takes place. ClimSel C7 is charged at a temperature exceeding 9°C/48°F. The freight is then placed in a transport box with ClimSel and the transport begins.
2. ClimSel C7 is now in a liquid state. The ambient temperature load (the cold) causes the freezing process to begin. Instead, the energy is consumed by the phase change and the melting process begins. Thus, the climate in the transport box is maintained, within the pre-determined range and there is no significant reduction in temperature.
3. Only when the PCM has completely solidified does the temperature begin to fall.
The phase change graph presented on each product sheet shows both the freezing and melting curves, as well as the typical range for temperature stabilisation. For the ClimSel C7 example, this is 2-8°C/35–46°F.
