Cann Systems Heat Pumps: Elevating Cannabis Drying

Selecting the ideal climate control system for your cannabis drying operation is a pivotal decision that can significantly impact the quality of your product and energy efficiency. At Cann Drying Systems, we’re dedicated to helping you make an informed choice. Let’s compare two common climate control technologies: the efficient Cann Drying Systems Heat Pump and the less efficient Thermoelectric (TE) system, to help you identify the best solution for your needs.

Unveiling Cann Systems Heat Pump Climate Control:


A heat pump is a mechanical device that transfers thermal energy from a colder medium to a hotter medium, using the reverse refrigeration cycle. Essentially, it can extract heat from one source and transfer it to another. Heat Pump systems stand out as the hero in the climate control arena, offering impressive advantages.

  • Scalability and Efficiency: Cann Systems Heat Pumps shine when it comes to handling larger load capacities without a notable increase in energy consumption. They consistently remove moisture efficiently no matter the ambient conditions.
  • Unfazed by Ambient Conditions: Regardless of ambient temperature variations, Heat Pump systems maintain temperature and humidity, ensuring reliable operation under varying conditions. Heat pumps are built to operate at setpoint whether ambient temperature is zero or a hundred degrees.
  • Dehumidification Prowess: These systems feature cooling compressors that lower humidity and dew points, condensing moisture within the drying space and efficiently removing ambient free water.
  • Energy Efficiency: Heat Pump systems intelligently cycle based on humidity setpoints, leading to significant energy savings.
  • Longevity: In the longevity race, Heat Pump systems outperform their counterparts, ensuring sustained performance and value.

While there are very few, we do need to list the shortcoming of the heat pump climate control system. Due to the complexity, the upfront cost of purchasing and installing a heat pump system can be higher compared to a thermoelectric system. Luckily, Cann works with Upwise Capital to help pave the way for a smooth transaction with equipment financing.


Initial Cost: The upfront cost of purchasing and installing a heat pump system can be higher compared to a thermoelectric system at smaller scale.

Maintenance and Repairs: Although heat pumps are generally very durable and require little maintenance – they are mechanically more complex systems. On the off chance maintenance is required it is often best to have the manufacturer and their service team handle repairs.

Thermoelectric (TE) Climate Control: A Less Efficient Option:

These devices work on the principle of the Seebeck effect, which converts a temperature gradient into an electrical voltage. They consist of two different conductors connected in a circuit. When one side of the device is heated and the other side is cooled, it generates a voltage.


Simplicity and Reliability: Thermoelectric systems are generally simpler in design and have fewer moving parts. This can lead to increased reliability and reduced maintenance requirements.

Compact Size: They tend to be smaller and more compact, making them suitable for smaller-scale operations or situations where space is limited. 


Higher Costs: TE systems become cost-prohibitive at larger load capacities and in more spacious environments, demanding proportionate increases in the number of ceramic cells and power supply as capacity is increased.

Ambient Temperature Dependency: Their efficiency drops when ambient temperatures fluctuate significantly, rendering them less reliable in variable conditions.

Lack of Dehumidification: TE systems transfer heat without dehumidifying the air, leaving moisture content unaltered within the system.

Energy Hungry: Continuous operation during the drying cycle translates to higher energy consumption. In order to increase drying capacity, operators must increase in equal proportion the number of ceramic cells and energy input.

Sluggish Temperature Adjustments: TE systems generally lag behind in adjusting temperatures, resulting in slower temperature responsiveness to user set point.

Choosing the Optimal System for You:

Opt for a (Compressor) Heat Pump System, a Cann Drying System Heat Pump, if:

  • You are dealing with substantial quantities of wet product, exceeding 200 wet pounds.
  • You anticipate the expansion of your cultivation operation over time.
  • Reducing energy consumption and costs is a priority.
  • You want to have eligibility for energy tax credits and energy rebate incentives.
  • A dependable climate control system capable of operating efficiently under diverse ambient conditions is essential.
  • Your dry room will be located in a non-environmentally controlled space, such as a greenhouse, barn, or warehouse.
  • You seek a long-lasting, low-maintenance solution designed for durability.
  • A traditional dry room approach, including dehumidification, is your preference.

In summary, while both thermoelectric devices and Cann Systems Heat Pumps can be used for cannabis drying, heat pumps are typically more efficient and better suited for larger-scale operations due to their ability to control both temperature and humidity effectively. Thermoelectric devices can be used for smaller-scale applications or for specific temperature control needs, but they may not be as energy-efficient.
