MGJ 225 Pint Pro Ceiling-Mounted Dehumidifier

Fourth-Generation Cannabis-Specific Technology | Ceiling-Mounted Design | Continuous and Stable Dehumidification

Product Overview

The MGJ 225 Pint Pro represents our latest fourth-generation dehumidification technology, designed specifically for cannabis cultivation and controlled environment agriculture. With a ceiling-mounted design, it saves valuable floor space while maintaining stable humidity control.

This unit provides a dehumidification capacity of ≈106 L/day (225 Pints/Day), making it suitable for medium- to large-scale grow rooms, particularly in environments where low night-time temperatures and high humidity present operational challenges.

A single unit can effectively cover up to 10 × 1000W LED grow lights, providing reliable dehumidification and ensuring a balanced environment across multi-layer cultivation systems.

Technology Evolution in Cannabis Cultivation

Over years of research and hands-on practice in cannabis grow facilities worldwide, MGJ has continuously upgraded its dehumidification technology to solve real cultivation problems:

1. 1st Generation – Basic commercial dehumidifiers: relied on compressor stop/fan defrost cycles, poor low-temp efficiency, outlet air too warm.

2. 2nd Generation – Added electric defrost rods and anti-corrosion coatings on coils, faster defrost, improved durability.

3. 3rd Generation – Introduced the three-stage system:

   • Pre-condenser (on-demand heating)

   • Nickel-coated evaporator (core dehumidification, corrosion resistant)

   • Rear condenser (reheat and air balance)
     This solved frosting issues during night cycles and reduced HVAC load.

4. 4th Generation (Current) – Comprehensive redesign of airflow and internal circulation, replacing the copper tube pre-condenser with a larger plate heat exchanger. This significantly improves low-temperature stability, reduces defrost frequency, and enhances continuous dehumidification performance while saving installation space.

Key Features of MGJ 225 Pint Pro

MGJ 225 Pint Pro 吊顶式工业除湿机

第四代低温防霜・防腐升级｜天花安装节省空间｜为大麻种植而生

一、产品定位与场景

MGJ 225 Pint Pro 是 MGJ GrowMaster 面向 室内大麻种植与温控环境 打造的 第四代吊顶式除湿机。它将天花嵌挂安装、低温防霜、抗腐蚀材料与高效空气过滤集成在一体，在 5–45℃ 宽温区内实现 连续、稳定 的除湿控制，尤其适合：

• 多层立体种植 / 走道狭窄的温室或种植房

• 要求“地面零占用”的工艺与物流动线

• 夜间关灯易结霜、湿度反弹的低温时段

• 与空调/空气循环系统协同控温控湿的场景

典型应用：单台设备可覆盖 ≈10 盏 1000W LED 生长灯 的负荷，持续提供 ≈106 L/天（225 Pints/Day） 的除湿能力。

二、我们对大麻种植环境的长期研究（技术路线）

围绕“关灯低温易结霜、湿度难稳定、设备耐腐蚀”三大痛点，我们经历了四代技术演进：

1. 第一代：传统家商用思路，依赖压缩机停机+风机化霜；低温除湿效率下降明显，出风温度偏高。

2. 第二代：在蒸发器加入 电加热化霜，并对换热器实施 纳米镀镍防腐；化霜速度提升、耐腐蚀增强。

3. 第三代：提出 三段式换热结构——
   前置冷凝器（按需）→ 纳米镀镍蒸发器 → 后置冷凝器（再热），夜间微量升温抑制结霜，后段再热平衡出风温度、降低空调负荷。

4. 第四代（当前）：在第三代基础上，重新设计内部气流路径，优化风道与换热面积，将前置铜管冷凝器升级为更大通道的板式换热器，在低温条件下进一步提升防霜稳定性与除湿连续性，同时保持整机占用空间与安装灵活性。

研究结论：在种植房“日间灯开-夜间关灯”周期下，稳定的露点管理与抑霜机制，是实现 24/7 连续除湿 的决定性要素；材料耐腐蚀与出风温度管理，则与 能耗、空调协同、花品一致性 直接相关。第四代架构正是基于这一实践沉淀。

三、第四代吊顶式架构（MGJ 225 Pint Pro）

• 板式前置换热（按需参与）：夜间或低温时段对进风做微量热管理，使蒸发器工作点远离结霜区，减少化霜频次，保证除湿不中断。

• 纳米镀镍蒸发器（核心除湿段）：应对大麻种植环境常见的 肥料气体、硫化物与弱酸碱湿气，维持换热效率与使用寿命。

• 后置冷凝器（再热段）：将空气“除湿但不过冷”，减小对空调系统的反复负荷，有利于 能耗与露点的整体平衡。

• 天花安装与短风道设计：抬高空气回路，减少局部死角与占地；更适配 层架种植/窄通道 布局。

• MERV-13 高效过滤：兼顾除尘与运行稳定，降低冷凝器/蒸发器结垢风险。

四、与立式机协同：分层除湿方案

MGJ 225 Pint Pro 可与 MGJ-158L Pro 落地式防腐除湿机 组成“上层（吊顶）+ 下层（落地）”的分布式除湿系统：

• 吊顶机负责 冠层以上 空间除湿与再热，避免顶层热湿堆积；

• 落地机负责 底层与通道 的湿气回收，缩短空间湿度均衡时间；

• 两者共同减轻空调负荷，支持 24/7 连续控湿。

五、核心参数（来自产品实测与铭牌）

• 除湿量：≈ 106 L/天（225 Pints/Day）

• 能效指标：Energy Factor ≈ 8.2 pints/kWh （≈ 3.9 L/kWh）

• 空气量：≈ 1100 CFM / 1800 m³/h

• 工作温度：5–45℃

• 额定功率 / 电流：1150 W / 5.3 A

• 端到端工程服务：支持 负载计算、风道与设备布置、露点/露压策略 的工艺咨询与交付。

• OEM/ODM 合作：可定制外观涂装、品牌铭牌、控制策略与通讯协议（视项目评估）。

七、投资与运维收益（方法论）

• 稳定产出：低温时段抑霜 + 再热控温，使 RH 曲线平滑，减少批次波动。

• 体系能耗更优：与空调“协同而非对冲”，在同等工况下减少无效负荷。

• 可维护性：过滤易更换、可冲洗面板与合理检修空间，降低停机与人工成本。

八、快速选型建议

• 层架/走道型：优先用 225 Pint Pro（吊顶） 做基础负载，再按区域补充 158L Pro（落地）；

• 单层大空间：225 Pint Pro 作天花主力，结合 V-Flow 空气循环 打通冠层与底层微气候。
