RML-200 2HP Water Chiller — 200 L/H, 220V, for Medium Bakeries

The RML-200 is R&M’s most-ordered water chiller — the 200 L/H, 2HP model that suits the majority of medium bakeries, restaurant bakeries, and hotel central kitchens. It delivers mixing water at a controlled 5–25°C from a 130L stainless steel tank, runs on single-phase 220V (no three-phase wiring needed), and holds the temperature the bakery sets — batch after batch, season after season. Imported compressor, micro-computer control, automatic feed water, full protection system. The compact water chiller that makes production scheduling predictable.

Why the RML-200 Is the Most-Ordered Model

The 220V advantage. This 2hp water chiller runs on single-phase 220V/50Hz — standard commercial power in most of Africa, Southeast Asia, the Middle East, and Latin America. No three-phase wiring, no transformer, no electrical upgrade required. A bakery installs it the way it installs a mixer: connect the water line, plug in, set the temperature. For many buyers, the 380V requirement of the larger models is a practical deal-breaker. The RML-200 is the largest model in the RML series that avoids it — which is the main driver behind its order volumes.

The capacity sweet spot. At 200 L/H and 130L of stored chilled water, the RML-200 matches the daily water demand of a medium bakery producing 1,000–3,000 loaves per day, or a restaurant or hotel central bakery running a standard spiral mixer line. It sits between “too small for the volume” (RML-100) and “needs three-phase power” (RML-300). For a bakery installing its first dedicated chiller, or upgrading from a smaller unit, this is the natural model to specify.

The proven platform. The RML-200 shares the same build — imported compressor, 304 stainless tank, micro-computer controller, full protection system — as every model in the RML series. It is the specification that the majority of R&M chiller customers have running in production, which is the strongest reference available.

For a full comparison of the RML series from 100 to 500 L/H, see the RML series water chiller overview page.

What 200 L/H Means for Your Production

Output (200 L/H) is the chiller’s steady-state cooling rate: it brings 200 litres of water per hour to the set temperature and holds it there under normal ambient conditions.

Storage (130L) is the tank volume — the buffer of chilled water available on demand between compressor cycles.

In practice: A typical mixing batch uses 30–80 litres of water. The bakery draws from the 130L tank during mixing; between batches, the compressor re-cools the replenished water back to the set point. The combination of buffer and re-cooling rate means the RML-200 supports continuous mixing through a full production day without running the tank down. Even a high-volume morning session — 10 batches at 50L each — uses 500L total over several hours. At 200 L/H of re-cooling capacity over that window, the machine keeps pace comfortably.

Installation and Power Requirements

Power supply: Single-phase 220V/50Hz. The compressor draws 1.5KW; the pump draws 0.37KW. Total running load is under 2KW — a standard commercial circuit handles it. No special electrical work is required.

Water connection: Connect the inlet to a standard mains water supply. The float ball valve in the tank manages the water level and refills automatically — no manual topping up.

Location requirements: Install in a ventilated area below 35°C ambient, away from direct sunlight, dust sources, and heat-producing equipment. The 800×600mm footprint places it against a wall or in an equipment corner. Leave airflow clearance around the condenser grille — blocked airflow causes high-pressure faults and reduces cooling efficiency.

Footprint note: This is a small water chiller for a commercial category — 800×600mm base and 1,360mm height. It moves on four swivel casters, which makes positioning and repositioning straightforward. Lock the casters once placed.

The Control Panel — What You See and What You Do

The RML-200’s micro-computer panel is designed for one daily operation: set the target temperature, then leave it running.

Status indicators (left column): LED indicators show Compressor / Pump / Heat / Temp.ok / Remote status at a glance — you can read the machine’s operating state from across the kitchen.

PV display: Shows the actual water temperature in real time — what the water in the tank is right now.

SV display: Shows the set temperature — what you have told the machine to hold.

Setting: Press Set, use the Up/Down arrows to adjust the target, press Set to confirm. The controller saves the setting automatically after 5 seconds without input. That is the full daily operation for most users.

Pressure gauges: The two analog gauges (HIGH pressure and LOW pressure) are the refrigeration circuit’s health indicators. Normal operating ranges are marked on the gauge faces. If either gauge reads outside the normal band, a fault code appears on the panel before anything fails.

Fault codes: E01–E08 cover sensor faults, high/low temperature alarms, pressure faults, phase sequence errors, flow switch triggers, liquid level alarms, and compressor overload — each with a specific alarm and reset procedure. The panel tells you what is wrong; the operating manual details the response for each code.

The Dough Temperature Difference — RML-200 in Daily Bakery.html Use

Without a water chiller: Tap water temperature follows the season. In a hot climate summer — common in Southeast Asia, Africa, and the Middle East — mixing water at 30°C or above causes dough to over-ferment and become sticky during mixing. Production timing drifts; the baker fights the dough; the bread that results varies from batch to batch and day to day.

With the RML-200: The baker sets 10°C in the morning — or whatever temperature the recipe calls for. Every batch that day uses 10°C water. Dough temperature is predictable; proofing runs on schedule; the same bread comes out at 8am and at 6pm. For a bakery supplying customers who come back for the same product, this consistency is the machine’s value.

Sourdough and cold-process doughs: The RML-200’s 5°C lower limit covers cold-water sourdough mixing, where bakers use ice-cold water to keep bulk fermentation slow and develop flavor over an extended period. A dedicated 220v water chiller handles this reliably where tap water cannot.

الأسئلة المتكررة

Does the RML-200 need three-phase power?

No. It runs on single-phase 220V/50Hz — standard commercial supply. This is the primary reason it is the most-ordered model in the RML range. The RML-300 and RML-500 require three-phase 380V; the RML-200 does not.

What is the difference between the RML-200 and the RML-100?

The RML-200 produces 200 L/H (vs. 100 L/H on the RML-100), has a 130L storage tank (vs. 100L), and runs a 2HP compressor (vs. 1HP). Both are 220V single-phase. The RML-200 is the right choice for a medium bakery; the RML-100 suits a small bakery or cake shop with lighter daily water demand.

What temperature range can I set on the RML-200?

5–25°C. The anti-freeze protection holds the evaporator safe at the low end. Setting below 5°C risks icing the evaporator — the manual specifies 5°C as the minimum. 25°C is the practical upper limit for a chilled-water system.

What is the water chiller 200 ltr price?

Contact us with your quantity and destination for a current factory-direct price. We respond within one business day with a confirmed quotation.

How often does the RML-200 need maintenance?

Routine maintenance: clean the condenser fins regularly (dust buildup reduces airflow and triggers high-pressure faults), clean the water tank and water filter periodically, and check the float valve function. The fault code system alerts you to issues before they become failures. No specialist refrigeration engineer is needed for routine upkeep.

Can I use the RML-200 as a mini water chiller for a small operation?

The RML-200 is compact for its output class — 800×600mm footprint — but it is a full commercial unit at 130kg, not a benchtop appliance. For very small operations (a cake shop or single-mixer setup), the RML-100 is the more appropriate starting point. Contact us with your daily water volume and we will recommend the right model.

What warranty applies to the RML-200?

Contact us at quotation for warranty terms, which vary by quantity and destination. Replacement parts — compressor, pump, control board, pressure gauges — are available direct from R&M.
