Thermoregulation by diathermic oil

With this type of thermal control, the die is brought to the required temperature by circulating heated diathermic oil into the die channels.
There is a difference between mineral oils, obtained by distillation from crude oil, and synthetic fluids: both are mainly composed by hydrocarbons, but the latter have better ageing properties.

In fact, fluid decomposition produces volatile substances, called “low boilers” and high viscosity polymers called “high boilers”. The former, in both cases, must be vented out regularly to avoid pump cavitation, vapour locks or mechanical damage, while the latter are soluble only in synthetic fluids up to a given ratio (10-15%).

Due to its high boiling point, diathermic fluid allows die preheating to temperatures up to 300°C.

On the contrary, it should be stressed that when temperature increases, thermal conductivity (W/m*°K) decreases and specific heat (Kcal/Kg*°K) increases, thus inhibiting heat transmission.

Thermoregulation by pressurized water

It is necessary to maintain water in a liquid state even at higher temperatures to obtain an effective and efficient thermal regulation and to avoid scale formation.Precipitation of calcium carbonate and magnesium carbonate (main components of the incrustation commonly known as LIMESTONE) is directly linked to temperature increase and is at its maximum near the evaporation point.

Water thermoregulation plants must be equipped with especially reliable devices to ensure the lowest possible pressurization in relation to the maximum temperature attainable.

The most significant water properties for thermoregulation include:

It is therefore possible to utilise suitably filtered water from cooling towers, wells, closed cooled circuits.

the highest specific heat among common substances (1 Kcal/Kg/°C), which remains constant as temperature changes;the heat transmission coefficient by convection is nearly double the value of oily fluids;best heat transmission by conduction, compared to oily fluids;heat transfer properties remain constant throughout a wide range of temperatures (unlike oily fluids, whose specific heat increases and whose heat transfer capacity decreases as temperature rises);non flammability;low cost: the water to be used is not required to have specific chemical properties except for a total hardness between 10 and 20°F (average hardness).

Thermoregulators Series PD and MINI Oil/Water 90°/150°

The thermoregulators of the PD series, depending on the model, allow to reach a maximum temperature of 150 ° C: thermal oil (Series PD 2000) or pressurized water (P150H Series PD).The model PD NEXT uses a thermoregulation circuit "open" up to 90 ° C. From 90 ° to 140 ° C the circuit becomes pressurized allowing the achievement of a maximum value of 150 ° C.

The model PD FW is a thermorefrigerator open circuit where then you can get a maximum value of temperature of 90 ° C and a minimum value of 5 ° C.

The thermoregulators MINI series, depending on the model, allow to reach a maximum temperature of 150 ° C of thermal oil (Series MINIPLUS), or 130 ° C of pressurized water (Series MiniPad).

??In particular, the model MiniPad can reach a minimum temperature equal to that of the network, not having a heat exchanger but exploiting the potential of the direct cooling.

The very small dimensions make this series ideal for solving problems of space or to build a multi-zone thermoregulation at low cost.

All thermoregulators are equipped with electric pumps with mechanical seal for high temperatures, the hydraulic circuit is totally in stainless steel to avoid possible corrosion problems.

Thermorefrigerators

Series PD / PF – WATER / PRESSURIZED WATER

The industrial thermorefrigerators Climat series PD / PF, are cooling systems water condensed which allow the fluid to reach a minimum temperature of 5°C.
Into the thermorefrigerator a heating group is integrated. It is composed of an electrical resistor immersed into the tank and the maximum temperature reached is 95 ° C. The thermorefrigerator has very compact dimensions and inside there are 2 different electro-pumps with mechanical seal which allow both the continuous circulation between the evaporator and the tank, and the sending of the cooled fluid from the tank to the mould.The industrial thermorefrigerators climat series PF-RH 160-5, single and dual-zone, are electro-hydraulic units particularly suitable for heating and cooling of moulds with "special" channels, up to very low temperatures (5 ° C with cooling circuit) through pressurized water with high thermal exchange.

Quenching tanks

The quenching tanks is a device capable of cooling all pieces just cast, before they are cut or sent for further machining.
The system comprisesa stainless steel vat whose dimensions depend on the size of piece tobe cooled;a cooling unit;a continuous re-circulation pump between the tank and the heat exchangers;a remote panel that checks temperature and level inside the tank.

By using water (tower or cooler), this system is capable, through the electronic instruments on the display, of maintaining a suitable temperature inside the tank to have a good cooling effect on the casting and the subsequent deburring.

The pump continually takes water from the tank and, after pushing it through the heat exchanger, pours it back into the tank, thus creating a closed circuit and an even temperature. The heat exchanger has large conduits that prevent clogging both in the primary circuit (carrying the tank water) and the secondary (carrying water from the tower).
