Rank® machines
The Rank® machines generate electrical power and/or high-temperature heat from a low-temperature heat source, improving the economic and environmental benefits at processes.
First products developed by Rank® are the Organic Rankine Cycle (ORC). This technology is especially suitable for the revalorisation of low temperature and / or small power heat sources to produce clean electrical power and useful heat at lower temperature. Among the main applications of Rank® ORC equipment, waste heat recovery and the use of renewable heat sources stand out. These are systems of special interest when the useful heat is used in other processes to form cogeneration or trigeneration systems.
The latest products developed by Rank® are the High-Temperature Heat Pump, (HTHP). These systems allow the production of very high-temperature heat (up to 150 ° C) by consuming electric power. They are highly energy-efficient equipment when waste heat is available at a low temperature to reduce the temperature . Another application of the Rank® HP equipment is the simultaneous production of heat and cold, with a small supply of electricity.
In both cases, ORC and HP, Rank® offers machines that are capable of adapting to a great variety of temperatures and heating available/required.
Rank® general catalog
A Rank® machine for every need
Whatever your needs, we have a Rank® machine that can dit to it, through various products that cover a wide range of thermal and power levels.
The offer of Rank® products is divided into four categories ORC (LT, MT, HT and HTC) as a function of the input temperature of the heat source to the ORC machine. Then, each category is divided into three models (1, 2, 3, and 4), depending on the output electric power generated. Consequently, there is a Rank® machine capable of generating electricity efficiently for each specific case, at different temperatures and heat.
Therefore, the Rank® machines are connected to heat sources with inlet temperatures between 90 °C and 170 °C and thermal power input between 100
We also offer the MICRO category, which allows recovering heat between 20 and 45 kWt and 90 and 120 ° C.
HEAT PUMP
The Rank® HP product range supports a wide variety of heat source inlet and heat production temperatures. In turn, Rank® HP products are divided into 4 models (1, 2, 3 and 4) based on the levels of thermal power needed in the process. Therefore, there is a Rank® HP machine capable of generating useful heat at high temperatures efficiently in a wide range of heating capacities and temperatures.
All in all, Rank® HP units are capable of producing high-temperature heat between 100ºC and 160ºC, and heating capacity between 120 kWt and 2,000 kWt.
ORC
The Rank® LT category of products can take advantage of very low-temperature heat sources. The minimum operating temperature is 90 °C, and it can complement the electrical generation with the production of useful heat with temperatures of up to 50 °C.
When the heat source temperature of the ORC machine is between 120 °C and 150 °C, Rank® MT equipment offers excellent electrical performance. It is also possible to use the heat sink current for several low-temperature applications.
The Rank® HT machines maximize the electrical production when possible in heat source temperatures above 150 °C. Similar to the other Rank® categories, the heat produced in the heat sink of the ORC system can be used according to the application.
The Rank® HTC range of products is specially designed for cogeneration applications with high-temperature thermal needs, as it can produce useful heat as hot water at 80 °C. Moreover, it receives heat at temperatures up to 210 °C, when very high efficiency is achieved.
For very low power applications or demonstration/didactic installations, Rank® MICRO allows electric generation from heat sources of very low temperature (from 90ºC). Also, it is complemented with the possibility of using useful heat at temperatures up to 50 °C.
HEAT PUMP
When there are demands for useful heat with temperatures above 100°C, the Rank® HP equipment allows to take advantage of lower temperature heat sources and satisfy the demands of useful heat at a higher temperature. It is a high-temperature heat pump, with maximum temperatures of heat production of 140ºC and COP values of 4.
