Features:

• Kit includes everything required to build your Peltier Refrigeration system.
• All are designed to be used together and users need not source them separately and make alterations to use them together. 
• Use this kit to get started and understand the Refrigeration system. 

Applications

• DIY Aquarium Chiller: Keep sensitive nano-reef tanks or axolotl tanks at precise low temperatures (e.g., 18°C) even in Indian summers.
• CO2 Laser Tube Cooling: Maintain safe operating temperatures for small laser cutters (K40 style) to extend tube life.
• PC Water Cooling Loop: Sub-ambient CPU/GPU cooling (Warning: Condensation management required).
• Dehumidification: Circulate cold water through a radiator to condense moisture from the air.
• Beverage Dispenser: Build a "tap-chiller" that cools drinks instantly as they flow through the block.

Project Evolution

From Air to Liquid: If you have mastered basic air-cooled Peltier fridges (like the SKU: PRO4914), this Water Cooling Kit is your graduation to "Active Liquid Loops."

• The Upgrade: Air cooling is limited by surface area. Liquid cooling transfers heat 20x faster. This kit allows you to move the "cold" to a specific location (like a CPU or a tank) using flexible tubing, rather than being stuck with a fixed cold plate.
• Prerequisites: You will need a Water Pump (submersible or diaphragm) and Silicone Tubing. This kit is the engine, not the plumbing.
• Effort Level: Intermediate. Requires understanding of water loops, leak testing, and high-current power management.

Virtual Technician: Wiring & Safety

• ⚠️ Power Warning: This unit draws up to 20 Amps at startup.

• DO NOT use small 1A or 2A adapters. They will trip instantly or burn out.
• REQUIRED: A 12V 20A (240W) SMPS or a modified ATX Computer Power Supply.

• Probots Logic-Safe: The fans and Peltier are wired for 12V. Ensure your power wires are at least 14 AWG or thicker to prevent the cables from melting under the high current load.
• Water Safety: Always leak-test your water loop for 1 hour before turning on the power. Running the Peltier without water flow can cause the water block to freeze rapidly, potentially cracking the seal if expanded ice forms.

Package Includes:

• 1 x 180W 12V Thermoelectric Single Head Peltier Water Cooling Air Heating DIY KIT

Frequently Asked Questions (Technical FAQ)

• Does this kit come with a pump?
  No, this is the thermal engine only. You need an external water pump to circulate the liquid.
• Can I run this on a 12V 5A adapter?
  No. The unit requires 15A. A 5A adapter will shut down or fail.
• How cold can the water get?
  It depends on the volume of water and insulation. For 10 Liters, it can drop ambient temp by 10-15°C. It can freeze small amounts of static water.
• Is the water block aluminum or copper?
  It uses a high-density Aluminum water block. Avoid mixing with copper radiators without corrosion inhibitors (galvanic corrosion).
• Can I use this to cool a room?
  No. 180W is insufficient for room AC. It is for small enclosed spaces or liquid loops only.
• Which side is hot and which is cold?
  The side with the Fans is the HOT side (exhaust). The side with the Water Block is the COLD side.
• Can I use this for a CPU cooler?
  Yes, but you must insulate the motherboard against condensation, as it can reach sub-zero temperatures.
• Do I need to add thermal paste?
  No, the unit comes pre-assembled with thermal paste applied. Do not disassemble unless necessary.
• What is the tube size for the water block?
  It fits standard 8mm Inner Diameter (ID) tubing.
• Can I reverse the polarity to heat the water?
  Technically yes, but NOT recommended. The fans are designed to cool the heatsink side. Reversing it might overheat the Peltier module if the water side (now hot) doesn't dissipate heat fast enough.
• Does it turn off automatically?
  No, it runs continuously. You need an external Thermostat (like W1209) to control the temperature.
• Is it noisy?
  The fans generate moderate noise (approx 40-50dB), similar to a high-performance desktop PC.
• Can I use automotive coolant?
  Yes, automotive coolant or distilled water with anti-algae drops is recommended.
• What is the max pressure for the water block?
  It is designed for low-pressure loops (aquarium/PC pumps). Do not connect directly to high-pressure tap water.
• How long can it run continuously?
  It is designed for 24/7 operation, provided the fans are running and dust-free.
• Why are there 3 fans?
  To ensure the massive heat generated by the 180W operation is quickly removed, keeping the cold side efficient.
• Can I stack two of these for more power?
  Yes, you can run water through them in series (one after another) for double the cooling capacity.
• Does it include a power supply?
  No, the Power Supply Unit (PSU) must be purchased separately.
• What happens if the fan stops?
  The unit will overheat rapidly. Immediate power cutoff is required to save the Peltier module.
• Is this efficient for making ice?
  It can make ice in small quantities (on the block surface), but it is optimized for circulating liquid cooling, not flash freezing.
