What Is Water Chiller DV1920E-C?

RIGID Coaxial Chiller DV1920E-C is a compact water recirculation cooling system. The main idea was to provide efficient cooling while securing the overall size of the product remains minimal. Water chiller DV1920E-C is a robust, compact refrigeration-based chiller module for nearly every cooling application

As the demand for micro cooling is growing, RIGID is frequently approached by customers who wanted to make use of RIGID’s miniature refrigeration solution but also wanted a system that used their own controls and coolant loop. Based on these inquiries, RIGID has developed a compact water chiller DV1920E-C (24V) which provides purely the “guts” of the refrigeration system and allows the end-user to adapt the compact module directly into their system.

The coaxial chiller is widely applied to compact cooling equipment. It is why the dimensions of this coaxial liquid chiller are 330x200x150mm.

The Main Components of Compact Water Chiller

The water recirculation system designed by RIGID utilizes R134A coolant, which is a popular cooling solution on the market. The DC compressor, condenser, and evaporator are all compact. The water chiller especially uses stainless steel coaxial evaporator. It has the major advantage of extraordinary cooling performance because the fluids are spread out over the liquid tubes. It also contains a variable speed driver board, and filter drier. 

The coaxial chiller adopts SS-316 stainless steel. The material is eco-friendly, which might be important for those who want to show their care for the environment. Additionally, using a stainless steel evaporator ensures an economical alternative to cooling with tap water. 

It is possible to control the speed of the compressor. You can do that by connecting the control board and the drive board. That way, you can adjust the entire system to get different temperatures for your needs.

How Does the Water Cooling System Work?

The RIGID coaxial liquid cooling solution uses a simple working process. Since the system is circulating a liquid loop, it utilizes pumps and pipes or tubes to send liquid throughout the product. The refrigerant has the task of absorbing heat from the fluid. The water chiller DV1920E-C ensures optimal heat transfer to maintain the desired temperature at all times.

RIGID water chillers consist of a compact, hermetically sealed refrigeration system (including a miniature variable speed compressor and drive board, condenser, expansion part, and an evaporator). The system is fully charged with R-134a, insulated, and mounted to a baseplate to drop directly into the end application. The user connects their coolant loop to the evaporator and provides airflow over the condenser. The user can interface with the driver board to provide compressor speed control as desired.

The compact cooling solution – DV1920E-C is a subsystem that can integrate directly into various applications. The device uses affordable parts, which maintains an overall acceptable price. The product is lightweight and features a compact size, which implies it can fit into virtually any application.

Vertical Farming – the Future of Sustainable Farming

Vertical farming grows leafy greens without sunlight or soil in vertically-stacked troughs in a fully-controlled indoor environment. It’s better for the planet than traditional agriculture because it requires 95 percent less water, grows in half the time as traditional crops, doesn’t deplete the soil, and can be grown year-round and served locally — even in cold climates.
Here is how vertical farming looks, and where the RIGID coaxial chiller fits:

More than a dozen green veggies are available for cultivation, including several types of lettuce. Those are Salanova, Romaine, Red Oak Leaf, Butter, and Bib lettuce. That should cover all restaurants and other corporate needs.

The list of leafy greens doesn’t stop there. Amaranth is a unique plant with a combination of red, purple, and green colors. You can also try the unique red-veined sorrel, as well as its classic variation. Red komatsuna, which has more of a purple color, is a hybrid of mustard and spinach that is popular in Japan.

Joi Choi is a type of Chinese cabbage that reminds me of the famous bok choi. However, its stems are wider and leave darker. If you are looking for traditional frilled mustard, growing Japanese spider mustard Mizuna could be the right move. Green giant and scarlet frills mustard are also a good choices for vertical farming. Finally, don’t forget to try growing Astro arugula or Portuguese kale.

The great thing about small-home farming is that it shortens the time required to grow particular crops. Thanks to that, you have more room for trying out different plants until you find the one that fits your preference.

Edible flowers are an interesting addition to the range of plants supported. For example, growing chamomile is an excellent way of ensuring the guests in a restaurant always have fresh tea. You shouldn’t underestimate lavender and its wonderful aroma and soothing properties. Marigold, viola, and anise hyssop are also among the edible plants you can grow with these hydroponic farms.

These flowers have both functional and aesthetic purposes. They are all edible and can be a part of the meals. While they are growing, these flowers look attractive and spice up your case with various colors.
